Method and apparatus for controlling shape of a bearing surface of a slider

摘要

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.
