Sony's latest CD copy protection comes unstuck

"The latest improvement to Sony's CD "copy protection" technology can still be defeated with sticky tape or marker pens, New Scientist has found. But Sony warns the methods could damage the discs and drives.

Copy protected discs are designed to stop computer users converting music tracks to digital music files, such as MP3s, which can be easily distributed over the internet. Sony's key2audio is one type of copy protection and is designed to stop music discs playing in PC and Mac CD-ROM drives. Each protected disc comes with the warning: "Will not play in Mac/PC".

Most protection systems, including key2audio, introduce data to discs that confuse CD-ROM drives, but are ignored by CD audio equipment. Some older copy protected discs had a visible gap near the edge of the disc, between the copy protection data and the music data.

It was found that drawing with a marker pen or applying tape over the gap and copy protection data would sometimes let the discs play normally in computers, presumably by preventing the CD-ROMs from reading the data."
