compact disc (CD) (sh)




Molded plastic disc containing digital data that is scanned by a laser beam for the reproduction of recorded sound or Other information.

Since its commercial introduction in 1982, the Audio CD has become the dominant format for high-fidelity recorded Music. Digital Audio data can be converted to analog form to reproduce the original Audio signal (see digital-to-analog conversion). Coinvented by Philips Electronics and Sony Corp. in 1980, the compact disc has expanded beyond Audio recordings into Other storage-and-distribution uses, notably for Computers (CD-ROM) and Entertainment systems (videodisc and DVD). An Audio CD can store just over an hour of Music. A CD-ROM can contain up to 680 megabytes of computer data. A DVD, the same size as traditional CDs, is able to store up to 17 gigabytes of data, such as high-definition digital Video files.
