ABSTRACT:
An optical disk drive is composed of comprising a tracking actuator, a sled motor, a sled filter developing an output corresponding to low frequency components of displacement of the tracking actuator, a pulse generating unit responsive to the output of the sled filter to develop drive pulses for driving the sled motor, and an pulse waveform adjusting unit designed to adjust waveforms of the drive pulses. The pulse waveform adjusting unit adjusts a waveform of relevant one of the drive pulses in response to the output of the sled filter and polarity of previous ones of the drive pulses.
