Several other formats were further derived from these, including write-once audio and data storage ( CD-R ), rewritable media ( CD-RW ), Video Compact Disc ( VCD ), Super Video Compact Disc ( SVCD ), Photo CD , PictureCD, CD-i , and Enhanced Music CD . The first commercially available audio CD player , the Sony CDP-101 , was released October 1982 in Japan .

A compact disc or CD is an optical disc originally used to store music , in the form of digital audio , but now also used as a data storage device . Compact discs are made from a 1.2 mm thick disc of polycarbonate plastic coated with a much thinner aluminium layer which is protected by a film of lacquer. The lacquer can be printed with a label. CDs are available in a range of sizes but the most commonly available is 120 mm in diameter. A 120 mm disc can store about 74 minutes of music or about 650 megabytes of data. Discs that can store about 700 megabytes (80 minutes of music) have become more common. There are also less common 90, 99 and 100 minute discs, but they are not compatible with all CD writers or readers. The format of the disc, known as the ' Red Book ' standard, was laid out by the Dutch electronics company Philips , who own the rights to the licensing of the 'CD' logo that appears on the disk. In broad terms the format is a two channel (left and right, for stereo) 16-bit PCM encoding at 44.1 kHz . Reed-Solomon error correction allows the CD to be scratched (to a certain degree) without degradation of the contents. |
