Abstract
An air bearing slider includes an asymmetric taper for control of pressurization and suction force formation. The asymmetric taper is disposed on an edge of a slider to accommodate for the speed differential across the disc radial direction, thereby improving take-off performance, reducing sensitivity to skew angle and altitude variation, and reducing the severity of impacts during ramp loading and unloading. A leading taper intersecting a leading surface and air bearing surface of the slider is asymmetric about a longitudinal, bisecting plane of the slider. In another embodiment, side taper intersecting a side surface and air bearing surface of the slider is asymmetric about a latitudinal, bisecting plane of the slider. In another embodiment, rail taper intersecting a rail recess surface and air bearing surface of the slider is asymmetric about a longitudinal, rail-bisecting plane.
