Compact Disc is a digital, high density optical disc, used in high-fidelity stereo sound systems. Also used to store computer data.
The information is encoded as tiny pits on the surface of the disc, and is recovered by a laser, a sensor and a digital-to-analog (D/A) converter. These disks have largely superseded magnetic tapes, and have rendered long-playing vinyl disks and turntables obsolete. Abbreviation, CD.
