。[Scope of Claim for Utility Model Registration] In a magnetic device that positions a magnetic bed at a predetermined position by moving a pair of magnetic heads against a disc-shaped double-sided magnetic medium, the retracted position of the magnetic head is The cam mechanism includes a cam mechanism that changes the distance between two magnetic heads facing each other when the power is turned off and the magnetic heads are retracted, and when the power is turned on to the drive source of the cam, When the cam mechanism is operated by the drive source to widen the distance between the two magnetic heads, the cam drive source is cut off, and the force λ drive source is restored, the cam mechanism is activated by the restoring force. A dust adhesion prevention device for a magnetic head, characterized in that it is configured to operate in a direction that reduces the distance between two magnetic heads.
