RECORDABLE OPTICAL DISC, METHOD AND RECORDING DEVICE FOR RECORDING CSS PROTECTED CONTENT ON THE RECORDABLE OPTICAL DISC

摘要

Copyrighted material is currently only distributed on read-only media and is additionally protected using the Content Scrambling System, also known as CSS. To allow a more flexible distribution of the copyrighted material it is the desire of the copyright owner to be able to record the copyrighted material locally in a store on a recordable optical disc instead of distribution via read-only optical discs a recordable record carrier is provided where the wobble is absent in the disc recognition zone. A recorder able to record in the presence of a low amplitude wobble can record the CSS material on such a disc, yet the playback device is not able to detect the recordable nature of the optical disc and will determine the disk type as read-only, thus avoiding a rejection of the optical disc due to a detected combination of a recordable record carrier and CSS protected material on the optical disc.
