Abstract
A self-loading disc head slider includes first and second raised bearing surfaces having outside bearing edges which diverge from one another along a leg portion which extends from a leading portion to a waist portion of the first and second bearing surfaces. A cavity dam defines a sub-ambient pressure cavity between the first and second bearing surfaces. A leading contour extends from a leading slider edge an intersection with first and second bearing surfaces. A notch is positioned within a central region of the leading contour between the first and second bearing surfaces and has first and second side walls which extend from the leading slider edge to the sub-ambient pressure cavity, through the cavity dam. At least one of the side walls is non-divergent from a longitudinal slider center line at the intersection in a direction from the leading slider edge toward a trailing slider edge.
