Abstract

A glide head with at least one rail includes a tapered trailing end on the at least one rail. The glide head flies with a pitch angle over the surface of the disk, thus, by tapering the trailing ends of the rails of the slider, the lowest flying point of the glide head is the junction of the air bearing surface of the rails and the trailing end taper. Because the junction of the air bearing surface and the tapered trailing end is the closest point on the glide head to the surface of the disk, the point of contact on the glide head is moved forward from the trailing end of the glide head. The tapered trailing end advantageously increases the amount of material surrounding the lowest flying point of the glide head relative to conventional glide heads. Consequently, the glide head with the tapered trailing end wears slower than conventional glide heads, and thus has an increased life. Further, the glide head with a tapered trailing end flies at a lower fly height than conventional glide heads.
