CD Rom

A flat, plastic disc with digital information encoded on it in a spiral from the center to the limit, the outside edge. Digital information is encoded with a laser at near-microscopic size, allowing a large amount of information to be stored. The standard CD-ROM can hold approximately 650 megabytes of data, although new technology now allows larger capacities. CD-ROMs are read using CD-ROM drives, a now-common computer peripheral, and are burned with CD-Recorders[?], commonly referred to as CD Burners[?].

See Compact disc or Enhanced CD for more information.
