Abstract: A driving force transmission device superior in reliability with suppressed rotation fluctuation. The driving force transmission device has gearing reception portions, three arm portions and a press member. The gearing reception portions are formed in the inner circumference of a rotor. The arm portions extend from a shaft radially. The arm portions can be elastically deformed. The arm portions have engagement tooth portions for transmitting a driving force of the shaft to the rotor. The press member presses the rotor to bend the arm portions in the direction where the rotor is pressed. In that state, the gearing reception portions gear with the engagement tooth portions.

Abstract: Embodiments of the invention limit a pitch attitude angle of a magnetic head slider during loading without allowing gimbal stiffness of a flexure in an ordinary flying state to be increased. In one embodiment, a limiter formed by part of a flexure is disposed so as to provide a clearance from a lift tab formed by part of a load beam. A limiter clearance, if the clearance between the limiter and the lift tab is so called for convenience sake, must be maintained as a physical clearance when a magnetic head slider is in an ordinary flying state. The lift tab and the limiter are disposed on a side of an air inflow end of the magnetic head slider. The limiter clearance during unloading is thereby made small so as to allow proper and positive unloading operation.
