ABSTRACT:
A head slider is provided that includes a slider body having leading and trailing slider edges and first and second side edges. The body further includes an air bearing surface generally disposed within a bearing surface plane. A raised portion is positioned on the bearing surface plane and spaced apart from the leading edge. Also, a comb structure is provided having a plurality of raised protrusions positioned proximate and substantially parallel to the leading edge of the slider, wherein the plurality of raised protrusions form gaps throughout the leading edge.
