Abstract
The air bearing surface (ABS) of an air bearing slider is formed with etched pads and a leading edge shaped shallow etch step taper region that extends continuously between first and second sides of the slider. A first pad is formed on the slider and extends from the trailing edge between the first side and a central axis and has a first extension at the step taper region. The first extension has a leading edge that is angled toward the first side of the slider. A second pad is formed on the slider and extends from the trailing edge between the second side and the central axis and has a second extension at the step taper region. The second extension has a leading edge that is angled inwardly toward the central axis. The first pad and the second pad provide an air bearing surface (ABS) for the slider. A deep central recess is bounded by the first pad, the second pad, and the step taper region. The design realizes constant flying attitudes, fast takeoff, less sensitivity to disk velocity and skew angle, and less sensitivity to altitude variation.
