スクドライブ装置。[Claims for Utility Model Registration] The magnetic disk is rotated by the motor 17, and the rotation of the stepping motor 5 is controlled by the pulley.
In a device that transmits information to an arm via a belt to move a magnetic head attached to this arm to a predetermined position, the stepping motor 5 is turned on for a period after the device is powered on and until a ready signal is output. A fixed disk drive device characterized in that it rotates and rotates a motor 17 faster than normal operation.
