New CD copy-lock technology nears market
A new kind of copy-protected music CD will likely hit U.S. shelves early next year, as record label SonyBMG experiments with a technology created by British developer First 4 Internet, according to sources familiar with the companies.
Gilliat-Smith said his company has been waiting to improve its technology. Better-known companies Macrovision and Sunncomm have seen sporadic--and sometimes controversial--use of their products on CDs released around the world.
For several years, the major record labels have sought a way to protect CDs against unrestricted copying and "ripping," or transforming songs into files such as MP3s that can be swapped widely online. Early experiments proved unpopular, prompting reports that the discs could not play in certain kind of stereos, or might even damage computers.
