Abstract
A dual depth slider air bearing surface that enables the slider to achieve a ramp fly height profile near the textured landing zone of a disk. The air bearing slider includes a slider body on which a U-shaped leading ABS pad is defined near and along a leading edge (relative to a moving recording medium) and partially along each side of the slider body. A front step pad extends from the leading edge section of the leading ABS pad to the leading edge of the slider body, at a reduced height relative to the height of the ABS pad. An asymmetric rear pad is defined along a longitudinal axis of the slider body and proximate to a trailing edge of the slider body. Extending above the rear pad is a trailing ABS pad, which has an asymmetric profile with respect to the longitudinal axis of the slider. The trailing ABS pad has a curved bowing profile towards the front of the slider body on the leading edge side of the trailing ABS pad.
