AbstractA negative pressure air-bearing slider supports a transducer proximate a rotating disc. The slider includes a slider body having a surface with a leading edge, a trailing edge, and a first and second side edges. First and second raised side rails are positioned along the first and second side edges, respectively. A raised cross rail is positioned near the leading edge and extends between the side rails. A negative pressure cavity trails the cross rail and is positioned between the side rails. The negative pressure cavity develops subambient pressure during flight. A raised island forms an air-bearing surface positioned at the trailing edge and between the side rails. The island has a forward edge which is raised from the negative pressure cavity and is recessed from the air-bearing surface to increase pressurization of the air-bearing surface. The air-bearing surface increases lift and slider flying height at the trailing edge at low disc speeds. At high disc speeds, the air-bearing surface has a diminished effect relative to an increased subambient pressure effect of the negative pressure cavity which provides a more even flying height over inner and outer data tracks on the disc surface.
