Abstract

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.
