| 1. A method for determining a value of a calibration parameter in a disc drive, comprising:
A. generating a track traversing signal for driving a pick-up to traverse across tracks of a disc in accordance with the track
traversing signal that determines a path of the pick-up moving across the tracks;
B. generating a tracking error signal with the pick-up traversing across the tracks of the disc according to the track traversing
signal in step A; and
C. determining the value of the calibration parameter from the tracking error signal.
