Thereafter, a focus search is performed by bring the focus actuator up and down. In this case, the actuator is made to be driven in a pull-in range. Then, a waveform is obtained with a certain time interval as waveform data by minitoring the waveform with an A/D converter. Whether present gains are proper or not is judged by analyzing an error signal to be obtained at this time. Thus, optimum servo gains are automatically obtained by discriminating all media from the difference of the servo gains.
