British company C-Dilla plans to stop people playing music CDs on their home
computers so that they won鈥檛 be able to copy them, and in WO 00/74053 it reveals
how. All CDs start with a lead-in track, which contains an electronic 鈥渢able of
contents鈥� (TOC) listing the music, and a lead-out track at the end. CD-ROM
drives in computers only play what鈥檚 listed in the TOC, but normal CD players
usually go on playing until the disc ends. If deliberate errors are put in the
TOC, for example the lead-out is listed as coming immediately after the lead-in,
normal players still work. But CD-ROM drives are stopped dead in their tracks.
Even if the TOC describes music as 鈥渃omputer data鈥�, the CD-ROM drive gets
confused and won鈥檛 play it.
