Inventor: ONO KENICHI
IPC: G11B21/08
Filed: 2000-10-02
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of sound when normalizing the position of a pickup. SOLUTION: When normalizing the position of a pickup 14, a lead screw 29 is rotated by a stepping mortor, the pickup 14 is moved to an outermost peripheral position and a maximum value CTout corresponding to the outermost peripheral position is preset in a preset counter. The counter conducts counting operations proportional to the driving pulses being supplied to the stepping motor. The screw 29 is rotated until the measured value of the counter becomes zero. Thus, the pickup 14 is moved to the vicinity of the outermost track in the reed-in area of the optical disk to conduct setting up. When the pickup 14 is moved to the outermost peripheral position, disengagement occurs between engaging protrusions 27 and 28 provided on the pickup 14 and the screw 29 because the inclination between the gear shapes of the screw 29 and the protrusions 27 and 28 is beforehand properly designed.  Thus, even though the disengagement occurs, the protrusions 27 and 28 are still strongly engaged to the screw 29, no gear skipping sound is generated and a normalizing process is quietly conducted.
