IMPROVED TRACKING ERROR SIGNAL CALIBRATION METHOD, AND DISC DRIVE IMPLEMENTING SUCH METHOD.

摘要

A method for generating a calibration value (TESC) for a tracking error signal (TES) in an optical disc drive (1) comprises the steps of performing a jump towards a target track of an optical disc (2) inserted in said optical disc drive (1); during at least a part of the jump, calculating the calibration value (TESC) as an approximation of the average of a plurality of tracking error signal amplitudes (TESA(i)) corresponding to a plurality of track crossings.
