Abstract
An optical disk has a groove in a recordable medium. The groove has a constant angular velocity wobble that is BPSK-modulated. Such a wobble provides timing and address information.
Claims24
An optical storage medium comprising:
- a recordable medium;
- and
- a groove in the recordable medium, the groove having a constant angular velocity wobble, wherein wobble cycles of the groove form a plurality of concentric zones and wherein wobble cycles in the same zone are spatially coherent.
An optical storage medium comprising:
- a recordable medium;
- and
- a groove in the recordable medium, the groove having a plurality of wobble cycles that form a plurality of concentric zones, wobble cycles in the same zone subtending the same angle, wobble cycles in different zones subtending different angles.
