Abstract
An air bearing surface for use on a magnetic read/write head. The air bearing surface provides a stable flight profile while exhibiting exception load/unload characteristics through the use of a plurality of pads providing high pressure areas as well as a central cavity providing a sub-ambient pressure to counter the high pressure areas. The channel is set a predetermined distance from the leading edge of the air bearing, the predetermined distance being greater than with prior art designs. A channel extends from the leading edge to the cavity to allow airflow into the cavity. The channel and the set back of the cavity both act in conjunction to facilitate unloading of the air bearing by preventing excessive sub ambient pressures.
