A disc head slider includes a slider body having a leading slider edge, a trailing slider edge and a slider length measured from the leading slider edge to the trailing slider edge. First and second raised rails are positioned on the slider body, which have first and second bearing surfaces, respectively. A recessed area is positioned between the first and second side rails and has a recess floor. A first raised pad is positioned rearward of a midpoint along the slider length and includes a third bearing surface, which is generally coplanar with the first and second bearing surfaces. A convergent channel is recessed within the third bearing surface and trails a portion of the recessed area. The convergent channel includes a leading channel end open to fluid flow from the portion of the recessed area, non-divergent channel side walls and a trailing channel end closed to the fluid flow and forward of a localized region of the third bearing surface.
