ABSTRACT:
An optical disk comprises a first recording area for recording contents data and data for recording and reproducing the contents data, and a second recording area for recording secondary data on the contents recorded in the first recording area, the secondary data being recorded as stripe marks longer in radial direction. Further, the second recording area comprises a first section for recording control data on the second recording area, a second section for recording data not to be inhibited to be outputted from a recording and reproducing apparatus for the optical disk, and a third section for recording data to be inhibited to be outputted from a recording and reproducing apparatus. The control data recorded in the first section includes an identifier which shows whether said second recording area includes said third section or not. By using the data to be inhibited to be outputted in the second recording area, a copyright of contents is protected and illegal use of software is prevented.
