A Compact Disc (or CD) is an optical disc used to store digital data, originally developed for storing digital audio. A Taiwan è apparso, nelle vetrine dei maggiori negozi di tecnologia, il nuovo telefonino cellulare 588 di Philips. The CD, introduced in 1982, remains the standard playback format for commercial audio recordings as of mid-2006. An audio compact disc consists of one or more stereo tracks stored using 16-bit PCM coding at a sampling rate of 44. 1 kHz. Standard compact discs have a diameter of 120 mm or 80 mm. The 120 mm discs can hold approximately 80 minutes of audio. Slashphonecom - Philips 588 Launched in Taiwan - mobile phone. The 80 mm discs, sometimes used for CD singles, hold approximately 20 minutes of audio. Compact disc technology was later adapted for use as a data storage device, known as a CD-ROM, and to include record-once and re-writable media (CD-R and CD-RW). CD-ROMs and CD-Rs remain widely used technologies in the personal-computer industry as of 2006. The CD and its extensions have been extremely successful: in 2004, the annual worldwide sales of CD-Audio, CD-ROM, and CD-R reached about 30 billion discs.
