Abstract
A disc head slider includes a slider body having a disc-facing surface, a recessed area positioned on the disc-facing surface, and a raised rail positioned on the disc-facing surface adjacent the recessed area. The raised rail includes a bearing surface and a recessed step surface which is recessed from the bearing surface and is raised from the recessed area. A plurality of bearing pads are formed on the recessed step surface and have upper surfaces that together define the bearing surface. A non-bearing pad is formed on the recessed step surface and has an upper surface, which is generally coplanar with the bearing surface, and a pointed leading pad edge.
