Abstract
A thin film read/write head with a high performance inductive write section that demonstrates good physical pole tip geometry control and is simple and economical to process. The head delineates an air bearing surface, and includes a pedestal formed on a read section. The pedestal includes a back edge that defines a zero throat level which lies in a plane substantially parallel to the air bearing surface. A pole layer is formed over, and separated from the pedestal to define a write gap therebetween. The pole layer includes an angled edge so that a top yoke can be stitched therealong to the pole layer.
