Abstract: An air-bearing surface of a hard disk drive slider comprises a trailing edge wherein a magnetic transducer is coupled to the air-bearing surface. A leading edge is opposite from the trailing edge. A channel is coupled to the air-bearing surface wherein the channel comprises: a closure at a distal end proximal to the leading edge; a bottom surface; and a center of the channel approximately aligned colinear with a center of the magnetic transducer. In this configuration the channel generates significantly more negative pressure proximal to the leading edge thereby stiffening the air bearing during operation.

Abstract: An air bearing surface (ABS) for a head assembly for a data storage device is described. The ABS includes a member, comprising a first extended region and a second extended region, wherein these two regions define a channel. This channel is open to the leading edge (LE) of the ABS, and is configured so as to allow air to flow along the channel toward the trailing edge (TE) of the ABS. As a result, the pressure of the air flowing along the channel does not experience significant fluctuations in pressure until approaching the trailing edge.
