Abstract

When an unexpected shock is applied to the personal computer, a sharp edge of the load beam or a sharp edge of the flexure is contacted or collided to the surface of the magnetic recording disk to damage its surface, so that a desired read/write operation is not performed. The head support mechanism is divided into the three portions, i.e. a rear portion one end of which can be pivotally mounted, a front portion supporting a slider including a read/write head for reading data from the magnetic recording disk or writing data to the magnetic recording disk, and a flexible hinge portion connecting the rear portion and the front portion. In according to the present invention, a protection layer is provided on a surface of the rear portion opposing to the recording disk at a position adjacent to the flexible hinge portion. The protection layer is provided on a surface of the front portion opposing to the recording disk at a position adjacent to the flexible hinge portion. At least one extruded portions are provided on a surface of the rear portion opposing to the recording disk at position adjacent to the flexible hinge portion. The rear portion includes a metal plate opposing to the magnetic recording disk, and the metal plate is mechanically deformed to form the extruded portion, and the extruded portion is coated by an resilient layer made of a material selected from a group consisting of polyimide, rubber, epoxy resin, silicone rubber, polyvinylchloride, polybutadiene and polyetherurethane.
