  • Patent number: 7549212
    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.
    Type: Grant

  • Publication number: 20030174444
    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.
