ABSTRACT:
A disc head slider is provided and includes a slider body having a disc-facing surface which includes a bearing surface that is generally disposed within a bearing surface plane. An angled inside rail, an angled outside rail and a cavity dam are formed on the disc-facing surface. At least one of the angled inside rail, the angled outside rail and the cavity dam includes a surface portion that defines at least a portion of the bearing surface. A sub-ambient pressure cavity is formed between the angled inside and outside rails, and includes a cavity floor that is displaced from the bearing surface plane. At least one recessed surface is formed on the disc-facing surface and is generally positioned outside of the angled inside rail, the angled outside rail and the sub-ambient pressure cavity. The recessed surface(s) is further displaced from the bearing surface plane than the cavity floor.
