Abstract
An information handling system, such as a disc drive, including a base, a disc stack rotatably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly also includes a load spring and a slider attached to said load spring. The slider has an air-bearing surface. The air-bearing surface includes a first rail, a second rail and a depression positioned between the first rail and the second rail of the air-bearing surface. The depression further includes a first level surface and a second level surface. The first level surface of the slider is at a different distance from a surface of the first rail of the slider than the second level surface of the slider. The air-bearing surface may also include a divider located between the first level surface of the slider and the second level surface of the slider.
