Compact disc


 

Compact disc (or CD) is an optical disc used to store digital data, originally developed for storing digital audio. It is the standard playback format for commercial audio recordings today.

Name

Notwithstanding the variability of general usage between "disk" and "disc" http://www.bartleby.com/61/16/C0521600.html, the customary spelling is "compact disc", rather than "compact disk". This may be in large degree due to its status as a Philips trademark under that spelling.
