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:
“I come to this land to ride my horse,
to try my own guitar, to copy out
their two separate names like sunflowers, to conjure
up my daily bread, to endure,
somehow to endure.”
—Anne Sexton (1928–1974)
“The best protection parents can have against the nightmare of a daycare arrangement where someone might hurt their child is to choose a place that encourages parents to drop in at any time and that facilitates communication among parents using the program. If parents are free to drop in and if they exercise this right, it is not likely that adults in that place are behaving in ways that harm children.”
—Gwen Morgan (20th century)
