ABSTRACT:
The present invention includes a comparator that inputs a tracking error signal through one input terminal thereof, and a control circuit for producing a control signal that varies the reference level E of the comparator depending on an ROT signal which represents the rotational frequency of an optical disk. The control circuit varies the reference level E of the comparator depending on the rotational frequency of an optical disk. The comparator compares the varied reference level E with the tracking error signal, and outputs an off-track signal accordingly.
