ABSTRACT:
A stepping motor for driving a head carriage having a motor axis on which is provided a lead screw comprises a seat plate that forms a back end of the motor, said seat plate being provided with a projection that projects toward a radial direction of the motor axis. At the time of the alignment of a head and a disk, the stepping motor is rotated by rotating a jig which is engaged with the projection. Thus the stationary position of the head carriage along a direction of its movement is adjusted.
