Abstract
An information carrier includes information arranged according to a recorded format. The information includes format information indicative of parameters of the recording format such as start and stop addresses of user information. The information is recorded according to predefined encoding rules, which correspond to rules of a different recording format that prescribes a predefined location on the information carrier for recording the format information. However the predefined location includes a confusion pattern and the format information is recorded at a second location that is different from the predefined location. A non-compliant player is unable to read or copy the information carrier because the reading is disturbed by the wrong parameters of the recording format. A recorder is arranged for recording the confusion pattern and relocating format information, whereas a player is arranged to retrieve the relocated format information.
