Abstract
A negative pressure air-bearing slider includes a slider body having a surface with a leading edge, a trailing edge, first and second side edges and a longitudinal axis extending from the leading edge to the trailing edge. First and second side rails are positioned along the first and second side edges, respectively. A raised crossed rail extends between the side rails and has a leading edge and a trailing edge. A negative pressure cavity extends from the cross rail toward the trailing edge of the slider body and between the side rails. A pair of angled channels formed in the cross rail permit relatively more air to enter the negative pressure cavity when the slider flies with its longitudinal axis at skew with respect to air flow than when the slider flies with its longitudinal axis in parallel with respect to air flow.
