ABSTRACT:
A slider design is presented including a first structure that extends between the rails of the slider body and over at least the first third of the slider body. A second structure having a depth lower than the depth of the first structure is disposed adjacent to the first structure and between the rails. The present slider design provides a stiff air bearing that has a near-constant flying height over various radii of the moving recording medium. The present slider design also provides exceptional lift-off in a ramp unloading operation.
