A disc head slider is provided, which includes a slider body having a disc-opposing face with leading and trailing slider edges and a slider length measured between the leading and trailing slider edges. The disc-opposing face has a bearing surface and a recessed area which is recessed from the bearing surface. A convergent channel is recessed within the bearing surface and has a leading channel end open to fluid flow from the recessed area, channel side walls, a trailing channel end closed to the fluid flow, and a channel length measured between the leading and trailing channel ends. The trailing channel end is located rearward of a midpoint along the slider length and the channel floor is vertically contoured relative to the bearing surface along at least a portion of the channel length.
