Abstract
A method for providing an electronic lapping guide (ELG) for a structure in a magnetic transducer are described. The structure has a front edge and a back edge. The ELG includes a stripe having a top edge and a bottom edge. The method includes calibrating a sheet resistance of the stripe and calibrating an offset of the top edge of the stripe from the back edge of the structure. The method further includes terminating the lapping based at least on the sheet resistance and offset of the ELG.
