ABSTRACT:
An input is ciphered in at least one of a sector forming circuit13, a scrambling circuit14, a header appendage circuit15, an error correction encoding circuit16, a modulation circuit17and a synchronization appendage circuit18, used for processing input data for forming a recording signal. Not only key for ciphering itself in the circuits but also the information as to which of the circuits has been used for ciphering becomes the key for ciphering. This realizes ciphering difficult to decode by a simplified structure.
