Abstract
A head slider, usually employed in a recording disk drive, comprises a chamfered vertex defined at a corner of a polygonal bottom surface surrounded by a contour separated from a contour of an air bearing surface. Even when the chamfered vertex collides with the surface of a recording disk, a scratch or damage may be hardly generated on the surface of the recording disk, as compared with a keen vertex. The recording disk drive employing the head slider may enjoy an improved shock resistance.
