ABSTRACT:
The invention provides a magnetic head slider with uniform and controllable flying height through a range of skew angles. According to the invention, a transverse and negative pressure contour (TNP) slider comprises a support structure which carries at least two TPC type pads, each having a transverse pressurization contour along at least one side edge of its face, at least one NP type pad provided with a bearing face and a recess which develops a subambient pressure level, and an ambient pressure reservoir separating each TPC type pad from each NP type pad for preventing hydrodynamic interaction between the pads. The ambient pressure reservoir defines a cavity having a depth with respect to the face of each TPC pad sufficient to maintain substantially ambient pressure in the cavity during movement of the recording medium.
