Abstract
A recording head for a disk drive with a load/unload mechanism has an air bearing on one surface. The air bearing comprises a patterned set of three air bearing pads, at least five shallow pockets and one deep pocket. A narrow gap extends from the deep pocket and separates leading ones of the air bearing pads and shallow pockets from each other. The air bearing pads have unique, step-shaped geometry and the rear pad is virtually free of any shallow area. This configuration gives the air bearing superior performance characteristics over prior art designs with load/unload mechanisms.
