ABSTRACT:
In an optical disk player, the disk clamper magnet is so constructed as to prevent the resonance of the pickup actuator as the pickup approaches the inner circumference of the disk due to interaction between the clamper maagnet and actuator magnets as the clamper magnet rotates. This structure avoids the resonance problem which is especially prevalent when a pickup approaches an inner disk circumference during playing. Therefore, it is possible to prevent an increase in rate of occurrence of tracking errors or the like which hinder reproducing capability or even make the tracking servo inoperative in an extreme case.
