    摘要： The present invention is intended to provide a disk drive apparatus capable of suppressing the occurrence of undesirable vibration due to the imbalance of a disk and capable of carrying out high-rate transfer, wherein a balancer is formed so as to accommodate a predetermined number of spherical bodies in a ring-shaped track portion having a predetermined shape, and this balancer is provided so as to be rotatable integrally and coaxially with the disk. In addition, in the disk drive apparatus of the present invention, the ring-shaped track of the balancer is divided into plural tracks by partition walls or the like, and a ball used as a balance member is disposed so as to be movable on each divided track. Furthermore, the disk drive apparatus of the present invention is configured so that the disk is held on both sides or one side thereof by using four or more projections or rubber sheets.

    摘要： In a method of the present invention for controlling stepping motor, the stepping motor driving current is increased or reduced at a fixed inclination in proportion to the time to control the stepping motor effectively, and, a stepping motor driving current pattern is changed by ¼ cycle or more to synchronize the state of excitation between the stepping motor driving means and the stepping motor to control the pick-up very accurately. In addition, the disk apparatus of the present invention, which uses a stepping motor is provided with a pulse rate pattern variable means, a pulse rate change proportion measuring means, and a driving voltage variable means, and when the pulse rate and the pulse rate change proportion are low, the driving voltage amplitude is lowered to reduce surplus torque generation in the stepping motor.
