Claims

[Claim for Utility Model Registration] In a magnetic recording and reproducing device that records and reproduces various data on a rotatably supported magnetic disk, a magnetic head that records and reproduces various data is attached to the magnetic disk, and the magnetic head is referred to as a magnetic disk. a head carriage capable of moving linearly in the radial direction between an origin track and a final track; a feed screw shaft screwed onto the head carriage for reciprocating the head carriage; and a feed screw shaft for rotationally driving the feed screw shaft. a driving means; a ring body rotatably supported on the feed screw shaft and movable along the axis of the feed screw shaft; and a ring body screwed onto the ring body so as to fix the ring body to the feed screw shaft. 1. A magnetic recording and reproducing apparatus comprising: an engaging pin that comes into contact with a part of a head carriage to restrict movement when the magnetic head moves to a predetermined position near an origin track.
