Abstract

The invention relates to a method of copy detection of a record carrier. In one particular embodiment the table of content entries are mastered on the record carrier in a detectable non-standard way, e.g. the sequence of table of content entries is mixed or the number of repetitions is varied. According to another embodiment additional synchronization symbols are used in one or more subcode frames which can be detected by a read-out device in order to distinguish between an original or a copy of a record carrier.
