The embodiment further comprises a movable air bearing surface element positioned at the leading edge end of the base portion. Finally, the embodiment further comprises an actuator positioned at the leading edge end of the base portion and coupling the base portion to the movable air bearing surface element, the actuator selectively controllable to move the movable air bearing surface element relative to the base portion to alter an air bearing surface provided by the base portion and the movable air bearing surface element to thereby control a fly height of the slider.

Abstract: A method and apparatus are provided for adjusting recession of an element, such as a pole tip, in a transducer structure formed in a plurality of thin film layers on an edge of a slider. A pre-stressed structure is formed as part of the plurality of thin film layers on the edge of the slider. The pre-stressed structure has a level of material stress. The recession is measured relative to a bearing surface of the slider, and then the level of material stress is adjusted as a function of the measured to effect a corresponding change in the recession.

Abstract: A head for a magnetic drive that includes a substrate with a thermal expansion rate CTE1. A transducer in the head has a bond to the substrate and has a transducer thermal expansion rate CTE2 that is greater than CTE1. A restraint layer in the substrate has a bond to one side of the transducer and has a first restraint layer thermal expansion rate CTE3 that is lower than CTE1. The restraint layer restrains protrusion of the transducer beyond the substrate at higher operating temperatures.

Abstract: The slider and method of the present invention relate to a slider for a disc drive. The slider includes a substrate having a cavity and a filler within the cavity. The slider further includes a transducer that is positioned near the filler. The design facilitates controlling the relative thermal expansion between the transducer and substrate of the slider that is near the transducer. Compensating for the thermal expansion of the transducer provides a more consistent fly height of the slider during operation of the disc drive. In addition, the design adjusts the air-bearing surface of the slider such that the transducer does not extend below the rest of the slider as the transducer expands.

Abstract: A clamping apparatus for holding elements includes a first spring member and a second spring member. The first spring member has a rigid portion that applies the majority of force to the elements. The second spring member is attached to the first spring member. The second spring member is more flexible than the first spring member. The second spring member has a structure that accommodates dimensional variations in elements held by the clamping member.

Abstract: A method of controlling a shape of a bearing surface of a head slider is provided. The method includes obtaining a set of shape adjust patterns, wherein each pattern corresponds to a response in the shape of the bearing surface. Furthermore, the method includes generating a representation of the shape of the bearing surface of the slider. The representation includes a plurality of measurements of substantially the entire shape of the bearing surface wherein each measurement corresponds to a location on the bearing surface and a height of the associated location. Material stresses on a working surface of the slider are selectively altered within the obtained shape adjust patterns based on the representation in order to alter the shape of the bearing surface.
