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

摘要

A method for generating a calibration value for a tracking error signal in an optical disc drive comprises the steps of performing a plurality of N jumps towards respective target tracks of an optical disc inserted in said optical disc drive; in each jump, calculating a one-jump normalization value; calculating a multi-jump calibration value on the basis of the plurality of N one jump normalization values obtained from the respective jumps. A control signal for controlling the radial actuator of the optical disc drive is generated on the basis of a normalized tracking error signal, which is calculated on the basis of the tracking error signal and the multi jump calibration value. ® KIPO & WIPO 2007
