A base for a data storage system is provided having an inner facing surface and an outer facing surface. The base includes a motor well. Formed with inner surface of facing surface of the base includes a medium region, an actuator region and a dam. The medium region is defined by a medium region planar surface surrounding a portion of the motor well, a leading surface and a trailing surface. The actuator region is defined by an actuator region planar surface that is recessed from the medium region planar surface, the leading surface, the trailing surface and a remaining portion of the motor well. The dam has a dam planar surface that surrounds the remaining portion of the motor well and is positioned on the actuator region planar surface between the leading surface and the trailing surface.

A slider for a disk drive is disclosed. In one embodiment, the slider includes an air bearing pad that contains a read/write transducer. This particular air bearing pad is small. High pressures are exerted on this small air bearing pad while the slider is flying in vertically spaced to its corresponding data storage disk. Pressures in excess of 500 psi may exist on this air bearing pad. In any case, this air bearing pad provides a significant portion of the total lifting forces for flying the slider in vertically spaced relation to its corresponding data storage disk or the like. As such, any expansion of the air bearing pad toward the data storage disk during read/write operations does not result in any significant loss of fly height.
