摘要 |
A physical identification data (PID) addressing method using a wobble signal, a wobble address encoding circuit, method and circuit for detecting the wobble address and a recording medium therefor. When addressing physical identification information on a recording medium, which has land and groove tracks in which data can be recorded, using wobbles, a wobble signal obtained by phase modulating address information indicating the physical identification information and a wobble signal having only a carrier are repeatedly alternatively recorded on both walls of either of a groove track and a land track by way of time division multiplexing. Accordingly, land and groove addresses can be detected by the same method, and the land track can be easily discriminated from a groove track by making the sizes of the addresses different in the land and groove tracks.
