Abstract
PURPOSE:To move a slider at accurate speed even when an inexpensive motor is used, by driving the motor for the slider by a driving signal having the number of pulses corresponding to that of poles of the motor at the time of scanning. CONSTITUTION:The motor 8 is rotated by the driving signal outputted from a driving circuit 9, and the slider 3 on which a pickup 2 is loaded is driven in a radius direction. The driving signal is constituted of the pulse with a prescribed period T, and the number of pulses per one revolution of the motor is conformed to the number N of the poles of the motor 8. Also, the period T is set as equation T=L/NV assuming the quantity of travel of the slider 3 per one revolution of the motor 8 as L and the average moving speed of the slider 3 as V. In such a way, it is possible to drive the slider 3 at the accurate speed by the inexpensive motor 8.
