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 spaced from the trailing edge and recessed below the at least raised bearing surface;
- and
- a first 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 first recessed cavity surface to the at least one raised bearing surface and a cavity step from a second cavity surface to the first recessed cavity 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 each elevated above a stepped bearing surface and including a cavity channel between the opposed side portions having a recessed cavity surface recessed from the at least one raised bearing surface and the stepped 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.
