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. In addition, the limiter clearance made small during loading allows the absolute value of a pitch attitude angle of the magnetic head slider to be limited to a small one if the pitch attitude angle tends to become negative due to disturbances or vibration from the loading operation itself.
