Abstract
A calibration method for a control device of an optical storage medium drive includes generating a calibration-driving signal by a signal generator and then generating a sensing signal by a sensor according to the calibration-driving signal, determining whether each period of the sensing signal is suitable, and comparing suitable periods of the sensing signal with corresponding periods of the calibration-driving signal to determine a phase difference between the sensing signal and the calibration-driving signal so as to adjust gain of a control device of the optical storage medium drive according to the phase difference. The calibration method is capable of preventing the influence of unstable sensing signals and promoting the performance of the optical storage medium drive.
