METHOD AND APPARATUS OF CALIBRATING PARAMETERS UTILIZED FOR DETERMINING SERVO SIGNALS

摘要

A method and related apparatus for calibrating at least a parameter utilized for determining a servo signal of an optical disc drive. The method includes: (a) adjusting the parameter; (b) generating a first signal according to detecting signals outputted from one side of a photo detector; (c) generating a second signal according to detecting signals outputted from the other side of the photo detector; (d) generating an index value according to the first and second signals; and (e) if a criterion for the index value is satisfied, utilizing the parameter corresponding to the index as an optimum parameter for the servo signal.
