In a pick-up drive device, the pick-up drive device includes means for driving the motor in accordance with a tracking signal representing the amount of the pick-up for normal reproduction, and means for applying a drive signal to the motor to move the pick-up at high speed in order to move the pick-up at high speed. When controlling the above-mentioned motor so as to move it and play normally for a certain period of time,
A pick-up drive device characterized in that motor control is not performed using a tracking error signal.
