Blu-ray or Blu-ray Disc (BD, BRD) is a digital optical disc data storage format. It was designed to supersede the DVD format, in that it is capable of storing high-definition video resolution (1080p). The plastic disc is 120 mm in diameter and 1.2 mm thick, the same size as DVDs and CDs. Conventional (pre-BD-XL) Blu-ray Discs contain 25 GB per layer, with dual layer discs (50 GB) being the industry standard for feature-length video discs. Triple-layer discs (100 GB) and quadruple-layers (128 GB) are available for BD-XL re-writer drives. The name "Blu-ray" refers to the blue laser (specifically, a violet laser) used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs. The main application of Blu-ray is as a medium for video material such as feature films and physical distribution of video games for the PlayStation 3, PlayStation 4, and Xbox One. Besides the hardware specifications, Blu-ray is associated with a set of multimedia formats.
A new Blu-ray Disc promises to keep data fresh long after it might have decayed on other discs. The MDisc, developed by Utah-based Millenniata, will be available from June this year in a 25 gigabyte capacity.
Blu-rays can hold about ten times more than DVDs because Blu-ray players use special blue lasers to read them. But it took a while for scientists to figure out how to make those lasers work.

See how Bluray and the late HD DVD discs were made.
I took two hours of footage (random family stuff) and burned my first blu ray disc and it looked awesome on the big TV so i decided to print the disc since I had gotten into the habit of just using a sharpie on all the DVD's and this was the first blu ray (lol) I could have put a bit more thought into the printing but I think it turned out pretty good considering I was rushing a bit. I burned the disc with sony dvd architect and I rendered it first with sony vegas 11 then let sony dvd architect re-render it so it took about 4 hours total to burn the disc with the second rendering. There was 2 hours of footage on the disc which is 1 hour more than I could have done with the DVD so Im stoked to start using Blu ray all the time just to save space if nothing else but the picture quality ...
These days, Blu-ray Disc Players have more features than just watching an HD movie. Things like streaming movies or renting movies or even watching TV/music from the internet. Tech expert Veronica Belmont offers some tips on choosing a Blu-ray player over a DVD player and if this choice is right for you.
We'll show you how to burn a Blu-ray disc. With your Blu-ray drive installed with the appropriate software, all you'll need is a blank Blu-ray disc. We'll walk you through how you'd go about burning a Blu-ray disc using MediaSuite 9 in this episode and more @ butterscotch.com: http://bit.ly/gZ6jlP
This won't work on deep scratches but for everything else you're probably going to like it. I've been able to repair some pretty bad ones that were skipping the whole time. Occasionally I'll get one that doesn't take, but it's an easy fix for most.
This video will show you how to hook up and set up a Sony blue-ray disc/DVD player (BDP-S3200)
