Claims

[Claims for Utility Model Registration] (1) The device is composed of a magnetic head and a magnetic head support that supports the magnetic head, and a first annular projection is formed on the outer edge of the magnetic head support, and a first annular projection is formed on the outer edge of the magnetic head support. a second annular protrusion is formed inside the first annular protrusion so that a first recess is defined by the second annular protrusion; In a magnetic head support device that supports the magnetic head in a protruding state within a defined second recess, the magnetic head is moved by a minute amount downstream in the rotational direction of the magnetic disk within the second recess. 1. A magnetic head support device, characterized in that the magnetic head support device is protruded in a closed state. (2) In the magnetic head support device, a first groove is provided on the downstream side of the first annular protrusion in the rotational direction of the magnetic disk, the first groove communicating with the first recess and the outside of the magnetic head support; Claims for registration of a utility model, characterized in that a second groove is provided on the downstream side of the second annular protrusion in the direction of rotation of the magnetic disk, the second groove communicating with the second recess and the first recess. 2. The magnetic head support device according to claim 1. (3) In the magnetic head support device, a third groove is provided on the upstream side of the second annular protrusion in the rotational direction of the magnetic disk, the third groove communicating with the first recess and the second recess. A magnetic head support device according to claim 2, which is characterized in that the magnetic head support device is characterized in that: (4) In the magnetic head support device, the surfaces of the first annular projection and the second annular projection that face the magnetic disk are inclined at a predetermined angle toward the upstream side in the rotational direction of the magnetic disk. A magnetic head support device according to claims 1 to 3 of the registered utility model claims.
