Several major record labels are adopting a new family of copy-prevention techniques intended to limit "Casual" copying by compact disc owners using their personal computers. These employ deliberate data errors introduced into discs during manufacturing to cause incompatibility with PCs without affecting ordinary CD players. This paper examines three such recordings: A Tribute to Jim Reeves by Charley Pride, A New Day Has Come by Celine Dion, and More Music from The Fast and the Furious by various artists. In tests with different CD-ROM drives, operating systems, and playback software, the paper finds these discs are unreadable in several widely-used applications as of July 2002.
