摘要:
A clock tracking circuit and method uses a clock compensation signal to compensate for timing marks on a media disk. The clock compensation signal may compensate for at least one of improper clock track closure and written-in jitter of the timing marks used to produce the measured clock signal. The clock compensation signal may be used to control a controllable oscillator used to generate the clock signal that thereby provides a compensated clock signal.
