DVD is an optical disc storage format, invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995. DVDs offer higher storage capacity than Compact Discs while having the same dimensions.

Pre-recorded DVDs are mass-produced using molding machines that physically stamp data onto the DVD. Such discs are known as DVD-ROM, because data can only be read and not written nor erased. Blank recordable DVD discs (DVD-R and DVD+R) can be recorded once using a DVD recorder and then function as a DVD-ROM. Rewritable DVDs (DVD-RW, DVD+RW, and DVD-RAM) can be recorded and erased multiple times.

DVDs are used in DVD-Video consumer digital video format and in DVD-Audio consumer digital audio format, as well as for authoring AVCHD discs. DVDs containing other types of information may be referred to as DVD data discs.

History[link]

Before the advent of DVD, Video CD (VCD) became the first format for distributing digitally encoded films on standard 120 mm optical discs. (Its predecessor, CD Video, used analog video encoding.) VCD was on the market in 1993.^[4] In the same year, two new optical disc storage formats were being developed. One was the Multimedia Compact Disc (MMCD), backed by Philips and Sony, and the other was the Super Density (SD) disc, supported by Toshiba, Time Warner, Matsushita Electric, Hitachi, Mitsubishi Electric, Pioneer, Thomson, and JVC.

Representatives of the SD camp approached IBM, asking for advice on the file system to use for their disc as well as seeking support for their format for storing computer data. Alan E. Bell, a researcher from IBM's Almaden Research Center got that request and also learned of the MMCD development project. Wary of being caught in a repeat of the costly videotape format war between VHS and Betamax in the 1980s, he convened a group of computer industry experts, including representatives from Apple, Microsoft, Sun Microsystems, Dell, and many others. This group was referred to as the Technical Working Group, or TWG.

The TWG voted to boycott both formats unless the two camps agreed on a single, converged standard.^[5] Lou Gerstner, president of IBM, was recruited to apply pressure on the executives of the warring factions. Eventually, the computer companies won the day, and a single format, now called DVD, was agreed upon. The TWG also collaborated with the Optical Storage Technology Association (OSTA) on the use of their implementation of the ISO-13346 file system (known as Universal Disc Format) for use on the new DVDs.

Philips and Sony decided that it was in their best interests to avoid another format war over their Multimedia Compact Disc, and agreed to unify with companies backing the Super Density Disc to release a single format with technologies from both. The specification was mostly similar to Toshiba and Matsushita's Super Density Disc, except for the dual-layer option (MMCD was single-sided and optionally dual-layer, whereas SD was single-layer but optionally double-sided) and EFMPlus modulation.

EFMPlus was chosen because of its great resilience to disc damage, such as scratches and fingerprints. EFMPlus, created by Kees Immink (who also designed EFM), is 6% less efficient than the modulation technique originally used by Toshiba, which resulted in a capacity of 4.7 GB, as opposed to the original 5 GB. The result was the DVD specification, finalized for the DVD movie player and DVD-ROM computer applications in December 1995.

The DVD Video format was first introduced by Toshiba in Japan in November 1996, in the United States in March 1997 (test marketed),^[6] in Europe in October 1998, and in Australia in February 1999.

In May 1997, the DVD Consortium was replaced by the DVD Forum, which is open to all other companies.^[6]

Specifications[link]

DVD specifications created and updated by the DVD Forum are published as so-called DVD Books (e.g. DVD-ROM Book, DVD-Audio Book, DVD-Video Book, DVD-R Book, DVD-RW Book, DVD-RAM Book, DVD-AR Book, DVD-VR Book, etc.).^[1][2][3]

Some specifications for mechanical, physical and optical characteristics of DVD optical discs can be downloaded as freely available standards from the ISO website.^[7] Also, the DVD+RW Alliance publishes competing DVD specifications such as DVD+R, DVD+R DL, DVD+RW or DVD+RW DL. These DVD formats are also ISO standards.^{[8][9][10][11]}

Some of DVD specifications (e.g. for DVD-Video) are not publicly available and can be obtained only from the DVD Format/Logo Licensing Corporation for a fee of US $5000.^[12][13] Every subscriber must sign a non-disclosure agreement as certain information in the DVD Book is proprietary and confidential.^[12]

Etymology[link]

The official DVD charter documents specify that the basis of the DVD name stems from the term digital versatile disc.^[14] Usage in the present day varies, with Digital Versatile Disc,^[15] Digital Video Disc, and DVD being the most common.

DVD was originally used as an initialism for the unofficial term digital videodisc.^[16]

A newsgroup FAQ written by Jim Taylor (a prominent figure in the industry) claims that four years later, in 1999, the DVD Forum stated that the format name was simply the three letters "DVD" and did not stand for anything.^[17]

The DVD Forum website has a section called "DVD Primer" in which the answer to the question, "What does DVD mean?" reads, "The keyword is 'versatile.' Digital Versatile Discs provide superb video, audio and data storage and access—all on one disc."^[18]

Identification (MID)[link]

This unreferenced section requires citations to ensure verifiability.

This section appears to be written like an advertisement. Please help improve it by rewriting promotional content from a neutral point of view and removing any inappropriate external links. (January 2012)

The DVD is made of a spiral groove read or written starting at the center. The form of the groove encodes unalterable identification data known as the Media Identification Code (MID). The MID contains prerecorded information indicating the disc's original manufacturer, apart from any visible branding on the disc itself. Also included is the byte capacity and permitted burning speeds (dependent on both the recorder, or burner, as well as what the disc can handle). This information can be read on many disc authoring software products.

A MID code is generally seen to be more reassuring for individuals whose priority is the long-term storage of their data than just buying for the sake of a brand name. For example, members of the Internet community Club MyCE, which specialises in disc burning, maintain that anything not produced by Japanese disc manufacturers Verbatim or Taiyo Yuden will be of inferior burning quality and offer shorter longevity.

Verbatim and Taiyo Yuden have high-quality standards to ensure their discs are excellent, (and anything that fails their strict quality tests may be destroyed) whilst other famous disc manufacturers, such as CMC Magnetics Corporation or Ritek Corporation, tend to produce batches with varying quality, resulting in inconsistency and poor burning results. Another reason is the burner's firmware, a set of instructions as to how to interact with the disc, varies from burner to burner. They determine how well a burn will be, or even if it will finish at all. A burn that fails to record during burning or verifying, is referred to as a "coaster" - or an unusable disc. Several errors as such may be encountered when trying to play back the disc.

Additionally, it is the firmware that determines how well it supports the MID code. Samsung and BenQ burners for example tend to be more tolerant of less well-known MID codes, whilst a LG and a Matsushita burner (made by parent company Panasonic) might be a little pickier over what it can handle.

As a result, many disc producers have turned to "faking" MID codes in order to obtain better firmware support. UmeDisc, which produces discs on behalf of AOne, Tesco, Signellex, etc., may turn to faking a Taiyo Yuden MID or a Mitsubishi MKM MID (manufacturer for Verbatim) so the burner can interpret it better. An AOne 8x DVD-R disc uses a Taiyo Yuden MID (TYG02), although its real MID code should be UME01.

The cheaper brand of discs may turn to "outsourcing" their products. This is where a brand name of disc changes the manufacturer depending on who will sell them a batch of discs at the lowest price. Memorex is notable for changing their manufacturers frequently (one spindle of DVD blanks may be produced by one manufacturer whilst another spindle may be produced by another). Brands that outsource tend to obtain the lowest quality batches, and making them inconsistent for burning and long-term storage.

However, some brands of discs remain loyal to their supplier. Traxdata and Arita are Ritek-only brands, whilst Datasafe and Datawrite are supplied exclusively by CMC Magnetics.

As a movie delivery medium[link]

DVD was adopted by movie and home entertainment distributors to replace the ubiquitous VHS tape as the primary means of distributing films to consumers in the home entertainment marketplace. DVD was chosen for its superior ability to reproduce moving pictures and sound, for its superior durability, and for its interactivity. Interactivity had proven to be a feature which consumers, especially collectors, favored when the movie studios released their films on LaserDisc. When the price point for a LaserDisc at approximately $100 per disc moved to $20 per disc at retail, this luxury feature became available for mass consumption. Simultaneously, the movie studios decided to change their home entertainment release model from a rental model to a for purchase model, and large numbers of DVDs were sold.

At the same time, a demand for interactive design talent and services was created. Movies in the past had uniquely designed title sequences. Suddenly every movie being released required information architecture and interactive design components that matched the film's tone and were at the quality level that Hollywood demanded for its product.

As an interactive medium[link]

DVD as a format had two qualities at the time that were not available in any other interactive medium: enough capacity and speed to provide high quality, full motion video and sound, and low cost delivery mechanism provided by consumer products retailers. Retailers would quickly move to sell their players for under $200, and eventually for under $50 at retail. In addition, the medium itself was small enough and light enough to mail using general first class postage. Almost overnight, this created a new business opportunity and model for business innovators, such as Netflix, to re-invent the home entertainment distribution model. It also opened up the opportunity for business and product information to be inexpensively provided on full motion video through direct mail.

Capacity[link]

The basic types of DVD (12 cm diameter, single-sided or homogeneous double-sided) are referred to by a rough approximation of their capacity in gigabytes. In draft versions of the specification, DVD-5 indeed held five gigabytes, but some parameters were changed later on as explained above, so the capacity decreased. Other formats, those with 8 cm diameter and hybrid variants, acquired similar numeric names with even larger deviation.

The 12 cm type is a standard DVD, and the 8 cm variety is known as a MiniDVD. These are the same sizes as a standard CD and a mini-CD, respectively. The capacity by surface (MiB/cm²) varies from 6.92 MiB/cm² in the DVD-1 to 18.0 MiB/cm² in the DVD-18.

As with hard disk drives, in the DVD realm, gigabyte and the symbol GB are usually used in the SI sense (i.e., 10⁹, or 1,000,000,000 bytes). For distinction, gibibyte (with symbol GiB) is used (i.e., 1024³ (2³⁰), or 1,073,741,824 bytes).

Size comparison: a 12 cm DVD+RW and a 19 cm pencil.

Each DVD sector contains 2,418 bytes of data, 2,048 bytes of which are user data. There is a small difference in storage space between + and - (hyphen) formats:

Technology[link]

DVD-RW Drive operating with the protective cover removed.

DVD uses 650 nm wavelength laser diode light as opposed to 780 nm for CD. This permits a smaller pit to be etched on the media surface compared to CDs (0.74 µm for DVD versus 1.5 µm for CD), allowing in part for DVD's increased storage capacity.

In comparison, Blu-ray Disc, the successor to the DVD format, uses a wavelength of 405 nm, and one dual-layer disc has a 50 GB storage capacity.

Writing speeds for DVD were 1×, that is, 1,385 kB/s (1,353 KiB/s), in the first drives and media models. More recent models, at 18× or 20×, have 18 or 20 times that speed. Note that for CD drives, 1× means 153.6 kB/s (150 KiB/s), about one-ninth as swift.^[21][23]

Internal mechanism of a drive[link]

This mechanism is shown right side up; the disc would sit on top of it. The laser and optical system scans the underside of the disc.

With reference to the photo, just to the right of image center is the disc spin motor, a gray cylinder, with its gray centering hub and black resilient drive ring on top. There is a disc-shaped round clamp, loosely held inside the cover and free to rotate; it's not in the photo. After the disc tray stops moving inward, as the motor and its attached parts rise, a magnet near the top of the rotating assembly contacts and strongly attracts the clamp to hold and center the disc. This motor has an external rotor – every visible part of it spins.

The gray metal chassis is shock-mounted at its four corners to reduce sensitivity to external shocks, and to reduce drive noise from residual imbalance when running fast. The soft shock mount grommets are just below the brass-colored washers at the four corners (the left one is obscured). Running through those grommets are screws to fasten them to the black plastic frame that's underneath.

Two parallel precision guide rods that run between upper left and lower right in the photo carry the "sled", the moving optical read-write head. As shown, this "sled" is close to, or at the position where it reads or writes at the edge of the disc.

A dark gray disc with two holes on opposite sides has a blue lens surrounded by silver-colored metal. This is the lens that's closest to the disc; it serves to both read and write by focusing the laser light to a very small spot. Under the disc is an ingenious actuator comprising permanent magnets and coils that move the lens up and down to maintain focus on the data layer. As well, the actuator moves the lens slightly toward and away from the spin-motor spindle to keep the spot on track. Both focus and tracking are relatively quite fast and very precise. These servos are comparatively wideband.

To select tracks (or files) as well as advancing the "sled" during continuous read or write operations, a motor (it could be a stepping motor; one would hear it if it were) rotates a coarse-pitch leadscrew to move the "sled" throughout its total travel range. The motor, itself, is the gray cylinder just to the left of the most-distant shock mount; its shaft is parallel to the support rods. The leadscrew is the rod with evenly-spaced darker details; these are the helical groove that engages a pin on the "sled".

The irregular orange material is flexible etched copper foil supported by thin sheet plastic; these are "flexible printed circuits" that connect everything to the electronics (which is not shown).

DVD recordable and rewritable[link]

Sony DVD Read & Rewritable

HP initially developed recordable DVD media from the need to store data for backup and transport.

DVD recordables are now also used for consumer audio and video recording. Three formats were developed: DVD-R/RW, DVD+R/RW (plus), and DVD-RAM. DVD-R is available in two formats, General (650 nm) and Authoring (635 nm), where Authoring discs may be recorded with CSS encrypted video content but General discs may not.^[25]

Although most DVD writers can nowadays write the DVD+R/RW and DVD-R/RW formats (usually denoted by "DVD±RW" and/or the existence of both the DVD Forum logo and the DVD+RW Alliance logo), the "plus" and the "dash" formats use different writing specifications. Most DVD readers and players will play both kinds of discs, although older models can have trouble with the "plus" variants.

Some first generation DVD players would cause damage to DVD±R/RW/DL when attempting to read them.

Dual-layer recording[link]

Dual-layer recording (sometimes also known as double-layer recording) allows DVD-R and DVD+R discs to store significantly more data—up to 8.5 gigabytes per disc, compared with 4.7 gigabytes for single-layer discs. Along with this, DVD-DLs have slower write speeds as compared to ordinary DVDs. When played, a slight transition can sometimes be seen in the playback when the player changes layers. DVD-R DL was developed for the DVD Forum by Pioneer Corporation; DVD+R DL was developed for the DVD+RW Alliance by Philips and Mitsubishi Kagaku Media (MKM).^[26]

A dual-layer disc differs from its usual DVD counterpart by employing a second physical layer within the disc itself. The drive with dual-layer capability accesses the second layer by shining the laser through the first semitransparent layer. In some DVD players, the layer change can exhibit a noticeable pause, up to several seconds.^[27] This caused some viewers to worry that their dual-layer discs were damaged or defective, with the end result that studios began listing a standard message explaining the dual-layer pausing effect on all dual-layer disc packaging.

DVD recordable discs supporting this technology are backward-compatible with some existing DVD players and DVD-ROM drives.^[26] Many current DVD recorders support dual-layer technology, and the price is now comparable to that of single-layer drives, although the blank media remain more expensive. The recording speeds reached by dual-layer media are still well below those of single-layer media. A potential reason is how Dual Layer discs are not as well matured compared to the Single Layer discs, as well as consumers, on a whole, have no desire for increased burning speeds.

There are two modes for dual-layer orientation. With Parallel Track Path (PTP), used on DVD-ROM, both layers start at the inside diameter (ID) and end at the outside diameter (OD) with the lead-out. With Opposite Track Path (OTP), used on many Digital Video Discs, the lower layer starts at the ID and the upper layer starts at the OD, where the other layer ends; they share one lead-in and one lead-out.

DVD-Video[link]

DVD-Video is a standard for storing and distributing video/audio content on DVD media. The format went on sale in Japan in 1996, in the United States in 1997, in Europe in 1998 and in Australia in 1999.^[28] DVD-Video became the dominant form of home video distribution in Japan when it first went on sale in 1996, but did not become the dominant form of home video distribution in the United States until June 15, 2003, when weekly DVD-Video in the United States rentals began outnumbering weekly VHS cassette rentals, reflecting the rapid adoption rate of the technology in the U.S. marketplace.^[5][29] Currently, DVD-Video is the dominant form of home video distribution worldwide, although in Japan it was surpassed by Blu-ray Disc when Blu-ray first went on sale in Japan on March 31, 2006.

Security[link]

The Content Scramble System (CSS) is a Digital Rights Management (DRM) and encryption system employed on almost all commercially produced DVD-video discs. CSS utilizes a proprietary 40-bit stream cipher algorithm. The system was introduced around 1996 and was first compromised in 1999.

The purpose of CSS is twofold:

1. CSS prevents byte-for-byte copies of an MPEG (digital video) stream from being playable since such copies do not include the keys that are hidden on the lead-in area of the restricted DVD.
2. CSS provides a reason for manufacturers to make their devices compliant with an industry-controlled standard, since CSS scrambled discs cannot in principle be played on noncompliant devices; anyone wishing to build compliant devices must obtain a license, which contains the requirement that the rest of the DRM system (region codes, Macrovision, and user operation prohibition) be implemented.^[30]

While most CSS-decrypting software is used to play DVD videos, other pieces of software (such as DVD Decrypter, AnyDVD, DVD43, Smartripper, and DVD Shrink) can copy a DVD to a hard drive and remove Macrovision, CSS encryption, region codes and user operation prohibition.

Consumer restrictions[link]

The rise of filesharing and "piracy" has prompted many copyright holders to display notices on DVD packaging or displayed on screen when the content is played that warn consumers of the illegality of certain uses of the DVD. It is commonplace to include a 90 second advert warning that most forms of copying the contents are illegal. Many DVDs prevent skipping past or fast-forwarding through this warning.

Arrangements for renting and lending differ by geography. In the U.S., the right to re-sell, rent, or lend out bought DVDs is protected by the first-sale doctrine under the Copyright Act of 1976. In Europe, rental and lending rights are more limited, under a 1992 European Directive that gives copyright holders broader powers to restrict the commercial renting and public lending of DVD copies of their work.

DVD-Audio[link]

DVD-Audio is a format for delivering high fidelity audio content on a DVD. It offers many channel configuration options (from mono to 5.1 surround sound) at various sampling frequencies (up to 24-bits/192 kHz versus CDDA's 16-bits/44.1 kHz). Compared with the CD format, the much higher-capacity DVD format enables the inclusion of considerably more music (with respect to total running time and quantity of songs) and/or far higher audio quality (reflected by higher sampling rates and greater sample resolution, and/or additional channels for spatial sound reproduction). This DVD-Audio technique was first used by the brothers Lagkind.^{[citation needed]}

Despite DVD-Audio's superior technical specifications, there is debate as to whether the resulting audio enhancements are distinguishable in typical listening environments. DVD-Audio currently forms a niche market, probably due to the very sort of format war with rival standard SACD that DVD-Video avoided.

Security[link]

DVD-Audio discs employ a DRM mechanism, called Content Protection for Prerecorded Media (CPPM), developed by the 4C group (IBM, Intel, Matsushita, and Toshiba).

Although CPPM was supposed to be much harder to crack than DVD-Video's CSS, it too was eventually cracked in 2007 with the release of the dvdcpxm tool. The subsequent release of the libdvdcpxm library (which is based on dvdcpxm) allowed for the development of open source DVD-Audio players and ripping software, such as DVD-Audio Explorer.^[31] As a result, making 1:1 copies of DVD-Audio discs is now possible with relative ease, much like DVD-Video discs.

Blu-ray Disc/HD DVD[link]

In 2006, two new formats called HD DVD and Blu-ray Disc were released as the successor to DVD. HD DVD competed unsuccessfully with Blu-ray Disc in the format war of 2006–2008. A dual layer HD DVD can store up to 30GB and a dual layer Blu-ray disc can hold up to 50GB.^[32][33]

However, unlike previous format changes, e.g., audio tape to Compact Disc or VHS videotape to DVD, there is no immediate indication that production of the standard DVD will gradually wind down, as they still dominate, with around 75% of video sales and approximately one billion DVD player sales worldwide as of 3 April 2011. In fact, experts claim that the DVD will remain the dominant medium for at least another five years as Blu-ray technology is still in its introductory phase, write and read speeds being poor as well as the fact of necessary hardware being expensive and not readily available.^[5][34][35]

Consumers initially were also slow to adopt Blu-ray due to the cost.^[36] By 2009, 85% of stores were selling Blu-ray Discs. A high-definition television and appropriate connection cables are also required to take advantage of Blu-ray disc. Some analysts suggest that the biggest obstacle to replacing DVD is due to its installed base; a large majority of consumers are satisfied with DVDs.^[37] The DVD succeeded because it offered a compelling alternative to VHS. In addition, Blu-ray players and now defunct format HD DVD players are designed to be backward-compatible, allowing older DVDs to be played since the media are physically identical; this differed from the change from vinyl to CD and from tape to DVD, which involved a complete change in physical medium. As of 2011^[update] it is still commonplace for major releases to be issued in "combo pack" format, including both a DVD and a Blu-ray disc (as well as, in many cases, a third disc with an authorized digital copy). Also, some multi-disc sets use Blu-ray for the main feature, but DVDs for supplementary features (examples of this include the Harry Potter "Ultimate Edition" collections, the 2009 re-release of the 1967 The Prisoner TV series, and a 2007 collection related to Blade Runner). Another reason cited (July 2011) for the slower transition to Blu-ray from DVD is the necessity of and confusion over "firmware updates" and needing an internet connection to perform updates.

This situation can be best compared to the changeover from 78 rpm shellac recordings to 45 rpm and 33⅓ rpm vinyl recordings; because the medium used for the earlier format was virtually the same as the latter version (a disc on a turntable, played using a needle), phonographs continued to be built to play obsolete 78s for decades after the format was discontinued. Manufacturers continue to release standard DVD titles as of 2012^[update], and the format remains the preferred one for the release of older television programs and films, with some programs such as Star Trek: The Original Series needing to be re-scanned to produce a high definition version from the original film recordings (certain special effects were also updated in order to be better received in high-definition viewing).^[38] In the case of Doctor Who, a series primarily produced on standard definition videotape between 1963 and 1989, BBC Video reportedly intends to continue issuing DVD-format releases of that series until at least November 2013 (since there would be very little increase in visual quality from upconverting the standard definition videotape masters to high definition).^[39]

Use as backup medium[link]

Durability of DVDs is measured by how long the data may be read from the disc, assuming compatible devices exist that can read it: that is, how long the disc can be stored until data is lost. Five factors affect durability: sealing method, reflective layer, organic dye makeup, where it was manufactured, and storage practices.^[40]

The longevity of the ability to read from a DVD+R or DVD-R is largely dependent on manufacturing quality, ranging from 2 to 15 years,^[41][42][43] and is believed to be an unreliable medium for backup unless great care is taken for storage conditions and handling.

According to the Optical Storage Technology Association (OSTA), "manufacturers claim life spans ranging from 30 to 100 years for DVD, DVD-R and DVD+R discs and up to 30 years for DVD-RW, DVD+RW and DVD-RAM".^[44]

Biography[link]

She started playing music as a child, after having learned the basics of reading musical notation, seven years later she began to record songs on cassette tapes. Her real musical training begins at the age of thirteen, when she began to give concerts in the bars of Sao Paulo, playing music by Adoniran Barbosa, Marisa Monte and Chico Buarque. In 2008 she moved to Rio de Janeiro and began playing in bars, and she atracted the attention of famous musicians such as Caetano Veloso, Milton Nascimento, João Donato among others. Maria Gadu gained renown playing "Ne me quitte pas" by Jacques Brel for Jayme Monjardim, who was in preproduction of the television series Maysa - Quando Fala o Coração (Maysa, when the heart communicates). Maysa Matarazzo, singer and mother of the director, had been very successful in the 1950s and 1960s singing this song, among others. Gadú's version was soon included in the soundtrack of the series that would premiere in January 2009. Gadú also had a small acting part in the series. As 2009 began, Maria Gadú prepared her first album with Rio Slap.

Jorge Aragão (Portuguese pronunciation: [ˈʒɔxʒi araˈɡɐ̃w], (b. March 1, 1949 in Rio de Janeiro), birth name Jorge Aragão da Cruz) is a Brazilian musician, singer/songwriter, working in the genres of samba and pagode. He is a multi-instrumentalist, and plays the guitar, surdo, cavaco and banjo, among other instruments. In performance, he usually plays the cavaquinho most of the show, and sometimes the banjo.

Biography[link]

Aragão started his career in the '70s as a sambista at balls and in nightclubs. His songwriting career took off in 1977, when Elza Soares recorded his composition "Malandro" (with Jotabê). He was a founding member of Grupo Fundo de Quintal (nucleus of the pagode genre) and one of its main composers and lyricists, abandoning the band some time later to dedicate himself to a solo career. Almost every great samba interpreter (Beth Carvalho, Alcione, Zeca Pagodinho, Martinho da Vila) has Jorge Aragão compositions in their repertoire.

The first solo album, Jorge Aragão, came in 1982, from Ariola. Conversant in the carnaval carioca, he was a commentator for the samba school parades on the TV networks Globo and Manchete. With 12 records to his credit, he has toured the United States and performs in various cities in Brazil. Among his greatest hits are "Amigos... Amantes", "Do Fundo do Nosso Quintal", "Enredo do Meu Samba", "Ontem", and "Coisinha do Pai" (with Almir Guineto and Luiz Carlos da Vila), immortalized in the recording by Beth Carvalho, which was inserted in the Mars Pathfinder probe in the late '90s. A lot of songs considered samba classics and very well known by the singing public of the rodas de samba were written by Jorge.

With almost 30 years dedicated entirely to samba and Música Popular Brasileira, Jorge Aragão is still actively performing in Brazil, more popular than ever.

Jolin Tsai (Chinese: 蔡依林; pinyin: Cài Yīlín; Wade–Giles: Tsai I-lin; Pe̍h-ōe-jī: Chhoà I-lîm; born September 15, 1980) is a Taiwanese Golden Melody Award-winning Mandopop singer, dancer and actor. Tsai was the second top earner among Taiwanese singers in 2010 behind Jay Chou (周杰倫), with earnings of US$14.51 million that year.^[1] She is managed by Mars Entertainment Ltd (天熹娛樂).^[2]

Early life[link]

Though Tsai was introverted and shy as a child, she studied English intensively during her youth and eventually majored in English Literature at Fu Jen Catholic University. During her childhood years, Tsai developed an interest in singing and experimented with different vocal techniques after listening to the songs of popular female singers such as Teresa Teng and Faye Wong.^{[citation needed]}

Musical career[link]

Universal Music Taiwan (1998–2001)[link]

Tsai first started her singing career by taking part in an MTV singing competition at the age of 18. She won the top prize at the competition with her rendition of Whitney Houston's #1 hit "Greatest Love of All". She was then signed by Universal Music.

In July 1999, her first single "Living With the World" (和世界做鄰居) was released. It was sold in convenience stores and was a tremendous success,^[3] which led to the release of her first album, Jolin 1019, in September 1999. At that time, she was promoted as "The Girl Next Door," and was an instant hit with teenagers, earning her the title "Teenage Boy Killer"^{[citation needed]}. Jolin 1019 ended up selling more than 400,000 copies in Asia. With the success of her first album, she released her second album in May 2000, Don't Stop. Many of the hits from that album were well known throughout Asia as the album also became a tremendous success.^{[citation needed]} She also released her first photobook with pictures mainly taken in Hawaii.

Nearing the age of 21, Tsai changed her image in her third album, Show Your Love. The album was considered more mature and soothing.^{[citation needed]}, but it did not sell as well as her previous two albums. Her fourth album, Lucky Number, also failed to match the sales of her first two albums. Tsai's music career came to a halt when conflicts surfaced between her and her music company.^{[citation needed]} At the end of 2001, Tsai's contract with Universal Music ended and her first greatest hits compilation, Together was released. Tsai did not release any albums the following year, but she did release her second photo book, with photos taken in Thailand.

Sony Music Entertainment (Taiwan) (2002–2006)[link]

Tsai signed with Sony Music Entertainment (Taiwan) that year and got the biggest break of her whole career. Her first single with Sony Music "Spirit Of The Knight" (騎士精神) became a big hit that led to the highly anticipated release of her fifth album Magic (看我72變). The album topped the Taiwan album charts for three months. More than 300,000 copies were sold in Taiwan alone, and over a million copies were sold in Asia.^[4] The album contained many of her most well-known singles, including the hit dance song "See My 72 Changes" (看我72變) that brought Tsai back to the top of the charts, a song which some suggested was named after The Monkey King's 72 transformations.^[5] Other songs from the album, such as "Say Love You" (說愛你) and "Prague Square" (布拉格廣場) were penned by fellow Taiwan star Jay Chou. Her more dance-oriented album marked her first release in two years following her hiatus in 2002.

Tsai's sixth album Castle (城堡), released in 2004, was just as popular as "Magic" and became a top album in many Asian countries.^{[citation needed]} Just as with Magic, many songs on this album were written by Chou, her rumored boyfriend at that time.^{[citation needed]} The playful song "It's Love" (就是愛) and the rock ballad "Rewind" (倒帶), became two of Tsai's biggest hits. Prior to the album's release, she showcased her single "Pirates" (海盜), another song composed by Chou, at a mini-concert. She subsequently filmed one of the most expensive music videos in Taiwanese history for that song.^{[citation needed]}

Between Castle and her next studio album, Tsai released a remix album of her most popular dance songs called J9 New + Party Collection. Tsai featured two new songs in the CD, including the hit song "Signature Pose". Tsai sang the Mandarin version of "Mirage (Warriors In Peace)", the theme song for the film Warriors of Heaven and Earth.

On April 25, 2005, Tsai seventh album J-Game was released, become the longest running album on the Taiwanese album charts in 2005, with over 1 million copies sold throughout Asia in just a little over a month.^[6] The album featured many more hip-hop influenced tracks than before, though it retained the dance pop and love ballads in her previous albums. Tsai supposedly broke up with Chou around the time the album was recorded, but she was able to find other writers and producers, including Leehom Wang, another pop star who composed "Exclusive Myth" (獨佔神話). The first single of the album "Barbaric Game" (野蠻遊戲) was a huge hit across Asia^{[citation needed]} and it was followed by other singles including "The Greek Girl Next To The Wishing Pond" (許願池的希臘少女) (composed by rising Hong Kong singer Ivana Wong), "Sky" (天空), "Repeat Signs" (反覆記號), "I Really Miss You" (好想你) and "Eyes Half Shut" (睜一隻眼 閉一隻眼). During this time, Tsai rapped in the duet "真命天子" [Destined Guy] with fellow artist Show Luo, which was featured on his album Hypnosis Show. She performed that song with Show in his first solo concert at the Taipei Arena.

Late in 2005, Tsai released her J1 Live Concert DVD, presenting performances of hits from her albums Magic (看我72變) and Castle from a late-2004 concert in Taipei. Show Luo made a guest appearance in the performance of "Prove It". The DVD did not include Jay Chou's guest appearance in her concert, in which he danced together with Tsai. It was later placed in the DVD for her greatest hits compilation, J-Top.

In early 2006, it was announced that Tsai would be leaving Sony Music Entertainment (Taiwan), to join Capitol Music Taiwan, which released under the name EMI Music Taiwan.^[7] To prepare for her new album, Tsai worked to perfect her dancing and change her style again.^{[citation needed]} She won the Style Award at the 2006 MTV Asia Awards, where she performed her new single "Dancing Diva" (舞孃) with elements of yoga and various props including a ball and a ribbon.^[8]

In May 2006, Sony released a greatest hits compilation album called J-Top, which included two CDs and a DVD with two previously unreleased music videos and a 70 minute documentary on Tsai's time at Sony. In one of the two music videos, Tsai looks back on all her previous music videos.

In concert during 2007 in Singapore.

After the release of J-Top, her first album with EMI Music Taiwan Dancing Diva was released on May 12, 2006. This album became Tsai's biggest album yet, selling over 2 million copies in Asia.^[9] The album featured her released single "Dancing Diva" (舞孃) along with "Pulchritude" (玩美), "Mr.Q" (The music video for this song shows Tsai getting intimate with Hong Kong pop star Edison Chen.), and the bonus track "Attraction of Sexy Lips"(唇唇欲動) (a song she did as part of an endorsement deal with MaxFactor similar to Anita Mui's song "Hot Red Lips"). The album also featured two of the biggest hits in Asia during the year^{[citation needed]}: the upbeat "A Wonder in Madrid" (馬德里不思議) and the love ballad "Pretence" (假裝). She collaborated with friend and label partner Stanley Huang on the song "Nice Guy" (乖乖牌), which he also helped to write. Tsai had some writing duties on the album, writing the lyrics for the song "The Prologue" (開場白), which many speculated was written about Chou. The album was re-released in July as the "Perfect Celebration Edition" with a DVD featuring music videos of all eleven of the songs on the album. She has done the same thing for Magic, Castle, and J-Game as well.

During the fall of 2006, Tsai began her Dancing Forever World Tour, performing concerts to sellout crowds in Asia and then to audiences in North America and Australia. The huge opening concert in Hong Kong, which took place on her birthday, featured many special guests, including one of Hong Kong's top male artists Eason Chan, Taiwan's rising pop princess Rainie Yang, and Show Luo. Show and Huang also made surprise appearances in other stops of her tour. In the most shocking moment of her tour, she kissed fellow Taiwanese star Elva Hsiao on the lips during one of her concerts. Tsai made guest appearances at her friend Stefanie Sun's concerts, while she and Singaporean male artist JJ Lin took turns appearing at each other's concerts.^{[citation needed]}

Tsai released her third remix album, Dancing Forever (唯舞獨尊) in October 2006, which contained two CDs and a DVD. The first disc contained all new material, including the title track and theme for her tour "Dancing Forever", covers of songs by Chinese singers Sandy Lam and Faye Wong, and the duet "Marry Me Today" (今天你要嫁給我) that she recorded with her idol and mentor David Tao. In this album, she experimented with two other Chinese dialects — Taiwanese and Cantonese (the Canto version of "Pretence" is on the album). Up to this point, she had only released music in Mandarin and English. The second disc included remixes of three dance hits from Dancing Diva, while the DVD featured the LUX-sponsored mini-concert she performed in the summer in Kaohsiung where Huang and Taiwanese boy band Energy also performed.

A month later, Sony released another two-CD compilation album called Jolin Favorite Live Concert Music Selection. This album consisted of remixes of popular songs Tsai recorded under Sony, as well as rare live tracks.

Tsai ended 2006 performing hits like "Mr.Q", "A Wonder in Madrid", "Pretence" and "Dancing Diva" at several New Year countdown parties in Taiwan. According to G-music, Dancing Diva became the biggest selling album of the year in Taiwan, while Dancing Forever reached #15 on the year-end album sales charts.^[10] Dancing Diva accounted for 4.26% of all Mandarin album sales in Taiwan for the year, ahead of Jay Chou's Still Fantasy, which accounted for 3.50%. Tsai's popular duet with Tao was considered by many lists to be the #1 song of the year in Taiwan^{[citation needed]}. Singles like "Dancing Diva," "Pretence," and "A Wonder in Madrid" also won many song awards between 2006 and 2007.^{[citation needed]}

On June 8, 2007, Tsai released her second DVD The Acquired Talent (地才), which featured performances from her latest world tour and documented her work in preparing for the tour. The DVD shows footage of her performing dance sequences with concert guests Luo, Huang, and Hsiao. The DVD opened at the top of the Taiwanese audio/video charts and stayed there for thirteen weeks.^[11]

On June 16, Tsai won the Most Favorite Female Artist and the Best Mandarin Female Singer Award for the first time at the 18th Golden Melody Awards.^[12][13] Her duet with David Tao won the Best Song Award. Tsai's win for Best Mandarin Female Singer drew criticism from netizens and industry critics, who believed her voice was not as strong as the other nominees (A-mei, Sandy, Angela Chang, and Penny Tai). However, many said that she won due to her all-round talent, hard work, and universal pop appeal.^[14] Regardless of the controversy surrounding this award, she won the Most Favorite Female Artist award following a fan vote conducted for a few months prior to the awards show, beating out many other artists such as A-mei, Fish Leong, Hsiao, Sun, Twins, and Yang.

Just a few days before the release of Tsai's new album at EMI Music Taiwan, Sony released another compilation album, Jolin's Final Wonderland (Jolin夢綺地精選). This collection featured almost all the songs Tsai released during her time at Sony in three CDs (The songs were separated into dance songs, cute songs, and love ballads.), as well as a DVD with 22 music videos and a 52-page photo book.

Jolin Tsai became the online game spokeswoman of "We Dancing Online" after the CD album release of "Dancing Forever".

Tsai's second album with EMI Music Taiwan, titled Agent J (特務J), was released on September 21, 2007. The album featured eleven new tracks - the title track "Agent J" (特務J), the ballads "Alone" (一個人) and "Fear Free" (怕什麼), the dance tracks "Bravo Lover" (愛無赦) (best known for its often-imitated dance steps^{[citation needed]}) and "Tacit Violence" (冷‧暴力), and the bonus track "Let's Move It," which was used as a promotional track in commercials for Toyota. The deluxe version of the album contained a 3-part 70-minute music movie filmed in France, London, and Bangkok. The movie, which cost NT$50 million to film, stars Tsai as the leather-clad Agent J and features popular Korean actor Kim Jae Won and Hong Kong stars Stephen Fung and Carl Ng.^[15][16] During the filming of the movie, Tsai had to learn two new forms of dance in 10 days: aerial silk dancing and pole-dancing. She almost paralyzed her right arm and fainted in the process.^[17]

According to G-music Taiwan, the album accounted for 45% of album sales and over 65% of Mandarin album sales in Taiwan in its first week of release. Since its release, the album stayed at the number one position for two weeks.^[18] Tsai released two more versions of the album: the Champion Special Edition (featuring 10 music videos, 4 dance instruction music videos, and a remix of Bravo Lover) and the No. 1 Special Celebration Edition (featuring the "Let's Move It" music video and her "Agent J" celebration concert with the best male artist at the Golden Melody Awards Nicky Lee from Taiwanese hip-hop group Machi).

Tsai then collaborated with Australian pop queen, Kylie Minogue in a song called "In My Arms", which would be included in the Asian version of Kylie's album X. Tsai was invited to the world premiere of Kylie's movie 'White Diamond', where Tsai presented Minogue with her newest album and a jade bracelet which Tsai personally picked for her.

Soon after, Tsai traveled to Hong Kong for Christmas, attending various functions and performing and winning three awards at the 2007 Metro Showbiz Music Awards, before returning to Taiwan. Tsai again ended off the year performing hits in Taiwan to celebrate the end of 2007. For the second year in a row, Tsai had the best-selling album in Taiwan. According to g-music, sales of Agent J accounted for 3.08% of all album sales in Taiwan and 5.96% of Chinese albums for the year, even higher than the numbers for Dancing Diva a year ago.^[19] Agent J also topped the year-end album charts according to Five Music, while The Acquired Talent was the best-selling music DVD of the year.^[20][21][22]

Like the previous year, Tsai also topped the Hito Top 100 Singles chart for the year. This time her song "Sun Will Never Set" was voted Top Song of the Year by over 340,000 voters.^[23]

In April 2008, Tsai incorporated newly learned skills such as flying rings and pole dance in addition to her usual multi-style dances in her concert in Beijing's Workers' Gymnasium.^{[citation needed]}
