disc - 1. An optical data storage device that is round, flat, and rigid. A laser writes data to and reads data from the hard plastic outer layer of the disc. Until recently, end users could only read from this type of storage, but advances have led to hardware devices enabling users to write to discs as well. CDs (audio and CD-ROMs) are the most popular form of disc now in use; although, Digital Video Discs (DVD) are becoming increasingly popular. See CD. See CD-ROM. See Digital Video Discs. Compare to disk.
2. A generic term for a direct-access optical storage medium which is read-only, as opposed to rewritable, including audio compact discs, CD-ROMs, videodiscs, etc. Compare with disk.
3. Alternative spelling of disk . Disc is often used for optical discs, while disk generally refers to magnetic discs, but there is no real rule.
