Abstract:
A self-loading disc head slider comprising:first and second raised bearing surfaces comprising a leading portion, a trailing portion, a waist portion, which is positioned between and narrower than the leading and trailing portions, and a leg portion, which extends from the leading portion to the waist portion, wherein the first and second raised bearing surfaces further comprise outside bearing edges which diverge from one another along the leg portion as the leg portion extends from the leading portion to the waist portion and wherein the leg portions are offset toward one another relative to the waist portions of the first and second raised bearing surfaces;a cavity dam defining a sub-ambient pressure cavity between the first and second bearing surfaces;a leading contour extending from a leading slider edge to an intersection with the first and second bearing surfaces; anda notch positioned in the cavity dam within a central region of the leading contour between the first and second bearing surfaces and having a notch floor, which is recessed from the first and second raised bearing surfaces and is raised from the sub-ambient pressure cavity, and first and second side walls, which extend from the leading slider edge to the sub-ambient pressure cavity, through the cavity dam, wherein 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.
