ABSTRACT:
A lapping guide system, method and article of manufacture is disclosed. A method of fabricating a lapping guide for use in conjunction with the machining of a magnetic recording transducer includes the following steps. A plurality of lap switch fingers of the lapping guide and a bottom pole of the transducer are fabricated at the same time and from the same material. Each lap switch finger has the same topology as the topology of the bottom pole. An insulating layer is fabricated on the plurality of lap switch fingers of the lapping guide and on the bottom pole of the transducer. A top conductor is fabricated on the insulating layer above a plurality of lap switch fingers, while a top pole is fabricated on the insulating layer above the bottom pole. The top conductor and top pole are fabricated at the same time and from the same material.
