ABSTRACT:
A slider air bearing surface design which significantly reduces the fly height sensitivity to contamination in the crossbar area. A structural feature at the leading edge provides contamination protection to the air bearing surface. The slider includes a slider body having an air bearing surface formed on a lower surface, wherein the air bearing surface comprises a crossrail and a central rail extending from the crossrail toward a leading edge for diverting debris from the air bearing surface to prevent accumulation thereon. The leading central rail includes a flared edge connecting the central rail to the crossrail, wherein the flared edge expands the width of the central rail toward the crossrail. A trailing center rail extends from the crossbar toward the trailing edge, and is narrower than the leading central rail. Further, the trailing center rail may be skewed relative to the sides of the slider body. The trailing center rail may also include a broadened support structure for supporting a transducer thereon. In addition, the side edges of the trailing center rail may be flared.
