摘要：There is provided an information recording apparatus (C1, C2, R1, R2) and so on capable of preventing illegally copied recording information (Sd) from being reproduced even if recording information (Sd) is illegally copied from an information recording medium (100) to another information recording medium (SP, 100) without being decoded. The cutting apparatus (C1) comprises a substitute information generator (17) for generating substitute information (Scg) by using identification information (Sid) unique to each DVD in which the recording information (Sd) is to be recorded, a substitute information writer (3) for generating substituted data signal (Sdr) by substituting the substitute information (Scg) for part of the recording information (Sd), and a light modulator (6) for recording the generated substituted data signal (Sdr) in a DVD which corresponds to the identification information (Sid) used for the generation of the substitute information (Scg).
