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.
