发明名称 Electrical lapping guide disposed laterally relative to a shield pedestal
摘要 Methods are provided for fabricating an electrical lapping guide, and for using the electrical lapping guide to fabricate a transducer of a magnetic recording head. Additionally, transducers comprising an electrical lapping guide are also provided. Methods of fabricating the electrical lapping guide comprise forming a resistive element proximate to a shield pedestal. Accordingly, the resistive element is both aligned with the shield pedestal in a transverse direction, and closely spaced from the shield pedestal in a longitudinal direction. The resistance of the resistive element correlates well with a throat height of the shield pedestal, and the correlation is utilized in the methods of fabricating the transducer. When a magnetoresistive stripe is uses as a second electrical lapping guide while fabricating the transducer, the two can be used to control a tilt angle in the transverse direction during lapping.
