Pneumatic buoyancy is generated by the interaction between the air baring slider 30 and a rotating disk 10 during the operation. This buoyancy is negated by the same and opposite spring force from a flexible hinge 32 and eventually the air baring slider maintains both of the small-sized objective lens and the RF coil at the regulated flying height from the disk surface without resistance. As a result, the operation at the stable floating height having reliability is made possible.
