Abstract
A signal generator generates a track traversing signal, and a driver causes a pick-up to traverse across tracks of a disc in accordance with the track traversing signal. An error signal generator generates a tracking error signal from the pick-up traversing across the tracks of the disc in accordance with the track traversing signal. A parameter calculator determines a value of a calibration parameter from the tracking error signal that is generated without delay and without signal distortion from low frequency components.
