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. At least one extruded portion is provided on a surface of the front portion opposing to the recording disk at position adjacent to the flexible hinge portion. The extruded portion is coated by a resilient layer made of a material selected from a group consisting of polyimide, rubber, epoxy resin, silicone rubber, polyvinylchloride, polybutadiene and polyetherurethane.
