Claims10
A disk recording medium comprising:
- a pregroove on which control information is recorded,
- said control information comprising disk-compatibility information, and
- said disk-compatibility information indicating a linear recording velocity corresponding to said disk recording medium.
A disk recording medium comprising:
- subcode data, said subcode data comprising disk-compatibility information, and
- said disk-compatibility information indicating a linear recording velocity corresponding to said disk recording medium.
A disk drive apparatus adapted for driving a disk recording medium on which disk-compatibility information is recorded, said disk-compatibility information indicating a linear recording velocity corresponding to said disc recording medium, and said apparatus comprising:
- reproducing means for reproducing said linear recording velocity from said disk recording medium;
- and
- control means for controlling said disk recording medium on the basis of the reproduced linear recording velocity.
A disk drive apparatus adapted for driving a disk recording medium on which disk-compatibility information is recorded, said apparatus comprising:
- reproducing means for reproducing said disk-compatibility information from said disk recording medium;
- and
- control means for controlling handling of said disk recording medium on the basis of the reproduced disk-compatibility information.
- wherein said control means controls the handling of said disk recording medium to prevent data from being recorded or reproduced on or from said disk recording medium when the apparatus determines that it is impossible to record or reproduce the data on or from said disk recording medium based on said disk-compatibility information.
