Abstract
A process of forming a two-piece pole for an inductive write head involves first forming a first pole piece having a width between opposite side surfaces defining a gap width of a transducing gap at an air bearing surface of the head. The process next involves forming a second pole piece having a first region remote from the air bearing surface and a second region extending from the first region toward the air bearing surface. The first region is wider than the width of the first pole piece. The second pole piece is formed so that at least a portion of the second region is contiguous a portion of the first pole piece and so that no sharp external corners exist between the first pole tip piece and the second pole piece within a pole tip region of the head.
