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.

Famous quotes containing the words copy and/or protection:
“Matisse makes a drawing, then he makes a copy of it. He recopies it five times, ten times, always clarifying the line. He’s convinced that the last, the most stripped down, is the best, the purest, the definitive one; and in fact, most of the time, it was the first. In drawing, nothing is better than the first attempt.”
—Pablo Picasso (1881–1973)
“Innocence does not find near so much protection as guilt.”
—François, Duc De La Rochefoucauld (1613–1680)
