Abstract: PURPOSE:To enable stable track jump operation by continuously generating a track jump signal from the start of a track jump until the track jump is almost finished and a tracking correcting signal corresponding to a tracking error in a track, which is the destination of the jump, is outputted. CONSTITUTION:A jump signal generating means 16 continuously generates the track jump signal from the start of the track jump until the track jump is almost finished and the tracking correcting signal corresponding to the tracking error in the track, which is the destination of the jump, is outputted. Namely, from the start of the track jump until the track jump is almost finished and tracking control is started in the track which is the destination of the jump, the track jump signal is continuously outputted and while the track jump signal is outputted, a tracking correcting signal (c) is not inputted to a driving circuit 10. Thus, the track jump is executed without being affected by the restoring force of an actuator and even when any force is operated to the actuator during the jump, the track jump is executed without fail.

Abstract: PURPOSE:To improve charge holding characteristic by setting a threshold voltage, in such a case that voltage is applied to a control electrode under the condition that a charge accumulation electrode is electrically neutral, to almost an average value of the threshold voltage after accumulation of charges and that after the discharging. CONSTITUTION:A threshold voltage of a memory cell in the neutral condition is set to almost an average value of the threshold voltages in the data writing condition and data erasing condition.
