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.

Slider having adjusted transducer recession and method of adjusting recession

A method and apparatus are provided characterizing the shape of a surface such as a bearing surface on a slider and for processing the shape. The shape is characterized by fitting a curve having a desired shape to measurement data and then determining residual deviations from the desired shape within localized regions. The surface is processed by selecting a material stress pattern to be applied to a working surface of the slider based on measured and desired contour shape parameters in a plurality of localized areas on the bearing surface. The measured contour shape parameter within a first of the plurality of localized areas is weighted more heavily than those within the other localized areas.
