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.
