It refers to a CD-ROM recording device. The legitimate uses of these are for reproducing back up copies of data on computers, and producing (legitimate) back-up copies of CD-ROM programs for personal use of the purchaser.

They are also being used for the illegitimate purposes of bootlegging CD's, software, and DVDs. This is heartily frowned on by just about every source of copywright authority out there, but, what can ya do?

The device itself uses blank CDs (mostly available as single use blanks), and also requires a PC to use.
