Physical identification data addressing method using wobble signal, wobble address encoding circuit, method and circuit for detecting wobble address, and recording medium therefor
A physical identification data (PID) addressing method using a wobble signal, a wobble address encoding circuit, a method and circuit for detecting the wobble address and a recording medium therefor. A wobble signal obtained by phase modulating address information indicating the physical identification information and a wobble signal having only a simple carrier are recorded in each groove track by way of time division multiplexing. Groove tracks are divided into odd groove tracks and even groove tracks, and a wobble carrier and wobble address information are alternately recorded in each groove track and between odd and even groove tracks such that the wobble address information is not recorded in a section of an even groove track corresponding to a section of an odd groove track in which the wobble address information is recorded. Therefore, interference between wobble signals of adjacent tracks can be removed, and a method and a circuit for detecting a wobble address can be simplified.
