Circuit for tracking error signal detection on an optical storage medium |
摘要 |
A circuit for tracking error signal detection on an optical storage medium, which has a plurality of digitizers, a plurality of logic comparators and a difference amplifier, is disclosed. The circuit involves summing the signals to be compared and obtaining a delay signal via a delayer. Therefore, the phase difference of the signals is detected via the delay signal to obtain the tracking error signal of the optical storage medium.
