Abstract
One embodiment of the present invention pertains to a slider that includes an aerodynamic surface which includes a first bearing surface, a cavity floor, and a first recessed pressurization surface. The first bearing surface is disposed on the aerodynamic surface, defining a bearing height. The cavity floor is disposed on the aerodynamic surface at a cavity depth below the bearing height. The first recessed pressurization surface is adapted to provide above-ambient fluid pressure when the slider is in nominal flight, which is greater than fluid pressure provided elsewhere on a trailing half of the aerodynamic surface at a substantial displacement from a longitudinal centerline of the aerodynamic surface. The first recessed pressurization surface is disposed on the aerodynamic surface at a recessed depth which is between the bearing height and the cavity depth.
