Copy Protection
The Red Book audio specification, except for a simple 'anti-copy' bit in the subcode, does not include any copy protection mechanism. Starting in early 2002, attempts were made by record companies to market "copy-protected" non-standard Compact Discs, which cannot be ripped, or copied, to hard drives or easily converted to MP3s. One major drawback to these copy-protected discs is that most will not play on either computer CD-ROM drives, or some standalone CD players that use CD-ROM mechanisms. Philips has stated that such discs are not permitted to bear the trademarked Compact Disc Digital Audio logo because they violate the Red Book specifications. Numerous copy-protection systems have been countered by readily available, often free, software.
