US Patent 7256965 Adaptable air bearing slider with trailing edge cavity

An air bearing slider including a recessed cavity surface to provide an adaptable bearing surface to compensate for thermal expansion or pole tip protrusion. The recessed cavity surface forms a leading edge cavity step to a raised bearing surface proximate to a trailing edge of the slider. The leading edge cavity step forms a rampless air bearing surface proximate to the trailing edge of the slider which is adaptable to form a ramp to pressurize a protruding surface of a transducer portion of the head.
