Abstract (en)
[origin: WO2004075193A1] Disclosed herein are a recording medium, an apparatus for forming the recording medium, and an apparatus and method for reproducing the recording medium. CPI (Copy Protection-related Information), identification information (CPI_Flag) indicative of recording or non-recording of the CPI, and/or a plurality of contents specific information (CSI) with different formats are recorded in a PIC (Permanent Information & Control data) zone of a high-density optical disc such as a BD-ROM (Blu-ray Disc-ROM). A formatting operation and mastering operation are performed under the condition that control data including the CPI, CPI_Flag and/or CSI is separated from main data. An optical disc device judges whether the optical disc has been illegally copied, with reference to the CPI, CPI_Flag and/or CSI read from the optical disc, and compulsorily stops a data playback operation upon judging that the disc has been illegally copied. Therefore, it is possible to effectively protect an optical disc from illegal copying, make an accurate and easy distinction between a legally made optical disc and an illegally made optical disc, and restrict reproduction of an illegally made optical disc.
