ABSTRACT:
A disc head slider for communicating with a rotating disc includes a slider body with leading and trailing slider edges, inside and outside slider edges relative to the disc, and a center line which extends from the leading slider edge to the trailing slider edge. A center rail is positioned substantially along the center line and includes inside and outside rail edges, a bearing surface and an edge step surface which is raised from the slider body and recessed from the bearing surface. The edge step surface extends along at least one of the inside and outside rail edges and has a greater area along the inside rail edge than the outside rail edge.
