Abstract
PURPOSE:To miniaturize a spindle motor, and to reduce its heat generation and noise by eliminating the adhesion phenomenon between a magnetic head and a magnetic disk by means of an auxiliary starter. CONSTITUTION:In case the spindle motor 11 does not start because of the adhesion phenomenon, the motor 11 is rotated to eliminate the adhesion phenomenon between the magnetic disk 1 and the magnetic head 2, for which the auxiliary starter 21 is provided. That is, if the rotary shaft 14 of the spindle motor 11 does not rotate within a determined time after energizing, a motor 22 is driven by a timer after the lapse of a determined time, and one side circular arc part 23c is frictionally brought into contact with the frictional contact plate 25 of a hub 18 to make the plate 25 rotate in the same direction of the rotation direction of the magnetic disk 1 forcively, and thereby the adhesion phenomenon between the head 2 and the disk 1 is eliminated. Therefore, the spindle motor can be miniaturized, accordingly, its heat generation and noise can be reduced.
