ARccOS Protection

ARccOS (Advanced Regional Copy Control Operating Solution) is a copy-protection system made by Sony that is used on some DVDs. Designed as an additional layer to be used in conjunction with Content Scramble System (CSS), the system deliberately creates corrupted sectors on the DVD, which cause copying software to produce errors (see bad sector). The corrupted sectors are in areas of the disk that most DVD players do not access, but most copying software does.
Despite being promoted as "fully compatible with available DVD players and drives,"DVD rippers have been designed to overcome ARccOS protection; it is also naturally overcome by using ddrescue, a Linux utility designed to copy images with errors.
