Abstract

A self-loading disc head slider includes a leading slider edge, a trailing slider edge and first and second raised side rails with first and second bearing surfaces, respectively. A cross rail extends between and is coplanar with the first and second raised side rails. A tapered surface is formed within the first and second raised side rails and the cross rail. The tapered surface extends from the leading slider edge to an intersection with the first and second bearing surfaces. A subambient pressure cavity is positioned between the cross rail and the trailing slider edge. A notch is positioned within the tapered surface, which extends from the leading slider edge to the cross rail and terminates prior to the intersection. The notch defines a leading edge of the cross rail along the tapered surface such that the leading edge of the cross rail is recessed from the first and second bearing surfaces.
