Abstract: One embodiment of 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, and at least one deep pocket. The three air bearing pads are spaced apart from each other by the deep pocket, with the largest of the air bearing pads located on the leading edge, and the other pads on the trailing edge. The air bearing pads have unique geometry one of the trailing corners of the air bearing is free of all the air bearing pads. This configuration gives the air bearing superior performance characteristics over prior art designs with load/unload mechanisms, particularly in regard to contact with the disk during loading and unloading sequences.
