ABSTRACT:
In the case where data are recorded in a medium, after a specific type of a medium in which recording is performed is set, if it is detected that information is recorded on an address of specific position at which decoding information is to be located, then data at a section in which the decoding information is located are replaced with predetermined information and recording is performed. Alternatively, when data are to be reproduced from a medium, after it is discriminated that data are reproduced from a medium of a specific type, if it is determined that data are reproduced from an address of specific position at which the decoding information is to be located, then reproduction data of a section in which the decoding information is located is replaced with predetermined information and outputted. Thus, when contents data are recorded in (or reproduced from) a medium such as a recordable DVD standard, copy of data requiring copyright protection can be limited easily and reliably while a recording area of a medium is being used effectively.
