Abstract
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.
Claims20
An air bearing slider comprising:
- a slider body, a leading edge, a trailing edge and at least one raised bearing surface proximate to the trailing edge and at least one stepped bearing surface recessed below the at least one raised bearing surface;
- and
- a recessed cavity surface recessed below the at least one raised bearing surface and the at least one stepped bearing surface and a leading edge cavity step from the recessed cavity surface to the at least one raised bearing surface to form an adaptive bearing surface.
An air bearing slider comprising:
- a slider body, a leading edge, a trailing edge and at least one raised bearing surface proximate to the trailing edge having a cross portion and opposed side portions and including a cavity channel relative to the cross portion and the opposed side portions of the at least one raised bearing surface having a recessed cavity surface recessed at least 1.0 μm from the at least one raised bearing surface and a leading edge cavity step from the recessed cavity surface to the at least one raised bearing surface proximate to the trailing edge of the slider.
