Abstract
The head slider mounts a recording/reproducing element and flies over a recording medium with the airflow generated when the recording medium moves. The head slider comprises a slider body having an air inflow end and an air outflow end, a rail projected from the slider body to define an air bearing surface extended to the outflow end, a projection formed on the rail and between the inflow end and the outflow end, and a recess formed at the outflow end of the rail to make narrow the width of the rail. When the recording medium stops, the head slider and the recording medium are in contact at the projection and the air outflow end of the rail. Since the outflow end of the rail is narrow in width, the stiction can be prevented. Moreover, it is unnecessary to form a projection near the outflow end of the rail and thereby the flying height of the recording/reproducing element can be lowered to improve the recording/reproducing sensitivity.
