Abstract

PURPOSE: To simplify a track detecting mechanism by providing a mechanical limit on a feed screw member for moving a head to the outside periphery further from a reference track provided on the outside periphery of a disk-like recording medium, and detecting a fact that the head exists in the outermost periphery of whether its screw turns or not.
CONSTITUTION: A magnetic head 1 is fixed to a head holding member 2, and this member 2 is coupled to a first guide shaft 3 like a round bar, and guided so as to be movable linearly in the radial direction passing through the rotation center of a magnetic disk rotation driving motor 30. Also, a second guide shaft 16 like a round bar is coupled to a groove 15 provided on one end of the member 2, and by the guide shaft 16 coupled to this groove 15, turning of the member 2 for using the guide shaft 3 as the rotation center is controlled. Also, to the tip of a shaft 8 for receiving a driving rotational force from a stepping motor 5, a rotation limiting member 40 for abutting on a rotation limiting member 2c of the member 2 which can move by turning, and limiting the turning of the shaft 8 is attached with a screw 40a, and turning of a projection 41 provided on the member 40 is detected by a photointerrupter 42.
