Abstract
A negative pressure air-bearing slider includes a slider body having a surface with a leading edge, a trailing edge and first and second side edges. First and second raised side rails are positioned along the first and second side edges, respectively. A raised crossed rail extends between the side rails. A negative pressure cavity extends from the cross rail to the trailing edge and is positioned between the side rails. A first isolation channel is disposed between the negative pressure cavity and the first side rail. A second isolation channel is disposed between the negative pressure cavity and the second side rail. The first and second isolation channels converge together toward the leading edge and communicate with the leading edge.
