ABSTRACT:
A magnetic head having an air bearing surface reads and writes data to and from a disc. The magnetic head includes a substrate and a data transducer positioned upon the substrate adjacent the a bearing surface. The data transducer includes a plurality of metallic layers wherein each metallic layer has a top surface. An isolated transducer portion is isolated from the data transducer and recessed from the air bearing surface. The isolated transducer portion has a top surface wherein the top surface of the isolated transducer portion is positioned coplanar to the top surface of one of the plurality of metallic layers of the data transducer.
