CD-ROM disk/CD-ROM: Common Errors in English Usage Entry for Thursday, July 18, 2013

CD-ROM disk/CD-ROM
“CD-ROM” stands for “compact disc, read-only memory,” so adding another “disc” or “disk” is redundant. The same goes for “DVD” (from “Digital Video Disc” or “Digital Versatile Disc”—there are non-video versions). Don’t say “give me that DVD disk,” just “give me that DVD.”
