The Disk II Floppy Disk Subsystem, often spelled as Disk ][, was a 5¼-inch floppy disk drive designed by Steve Wozniak and manufactured by Apple Computer. It was first introduced in 1978 at a retail price of US$495 for pre-order; it was later sold for $595 including the controller card (which can control up to two drives) and cable. The Disk II was designed specifically for use with the Apple II personal computer family to replace the slower cassette tape storage and cannot be used with any Macintosh computer without an Apple IIe Card.

Apple produced at least six variants of the basic 5¼-inch Disk II concept over the course of the Apple II series' lifetime: The Disk II, the Disk III, the DuoDisk, the Disk IIc, the UniDisk 5.25" and the Apple 5.25 Drive. While all of these drives look differently and they use four different connector types, they're all electronically extremely similar, can all use the same low-level disk format, and are all interchangeable with the use of simple adapters, consisting of no more than two plugs and some wires between them. Most DuoDisk drives, the Disk IIc, the UniDisk 5.25" and the AppleDisk 5.25" even use the same 19-pin D-Sub connector, so they are directly interchangeable. This is not the case with Apple's 3.5" drives, which use several different disk formats and several different interfaces, electronically quite dissimilar even in models using the same connector, and are not generally interchangeable.

A disc (International English) or disk (American English), from Latin discus, is a flat circular object. It may also refer to:

Howard Leslie Shore (born October 18, 1946) is a Canadian composer, notable for his film scores. He has composed the scores for over 80 films, most notably the scores for The Lord of the Rings film trilogy, for which he won three Academy Awards. He is also a consistent collaborator with director David Cronenberg, having scored all but one of his films since 1979.

He has also composed a few concert works including one opera, The Fly, based on the plot (though not his score) of Cronenberg's 1986 film premiered at the Théâtre du Châtelet in Paris on 2 July 2008., a short piece Fanfare for the Wanamaker Organ and the Philadelphia Orchestra, and a short overture for the Swiss 21st Century Symphony Orchestra.

Shore is a three-time winner of the Academy Award, and has also won three Golden Globe Awards and four Grammy Awards. He is the uncle of film composer Ryan Shore. Shore serves on the Board of Trustees at his alma mater, Berklee College of Music.

Shore was born in Toronto, Ontario, Canada, the son of Bernice (née Ash) and Mac Shore. He studied music at Berklee College of Music in Boston after graduating from Forest Hill Collegiate Institute. From 1969 to 1972, he performed with the group Lighthouse. In 1970 he was the music director of Lorne Michaels and Hart Pomerantz's short-lived TV program The Hart & Lorne Terrific Hour. Shore wrote the music for Canadian magician Doug Henning's magical/musical Spellbound in 1974, and he was the musical director for Lorne Michaels' hugely influential late-night NBC comedy show Saturday Night Live from 1975 to 1980, appearing in many musical sketches, including Howard Shore and His All-Nurse Band, and dressed as a beekeeper for a John Belushi/Dan Aykroyd performance of the Slim Harpo classic I'm a King Bee. Shore also suggested the name for The Blues Brothers to Dan Aykroyd and John Belushi.
