Abstract:
1. An air bearing surface (ABS) for a head assembly for a data storage device comprising: a member comprising a first extended region and a second extended region, wherein said first extended region and said second extended region define a channel, wherein said channel is open to a leading edge (LE) of said ABS, and wherein said channel is configured so as to allow air to flow along said channel toward a trailing edge (TE) of said ABS, such that a pressure of said air flowing along said channel does not fall significantly below an ambient pressure of the air, wherein said first extended region forms a surface level, wherein said surface level forms a plane nearest to a disk, wherein said surface level bounds said channel with two opposing channel walls and a channel wall near said TE wherein said first extended region of said member at least partially bounds a first low pressure area, wherein air that passes over said first extended region enters said first low pressure area, expands, and substantially depressurizes.
