Abstract:
A method for forming an electromagnetic transducer, the method comprising:forming a first soft magnetic pole layer having a substantially flat surface; forming an inorganic nonferromagnetic layer over said first pole layer, including forming an inorganic nonferromagnetic apex region having a first side that is substantially parallel to said surface and a second side that is not parallel to said surface and not perpendicular to said surface; and forming a second soft magnetic pole layer over said inorganic nonferromagnetic apex region, such that said second pole layer has an interface that is substantially equidistant from said second side; wherein forming said inorganic nonferromagnetic apex includes forming a photoresist mask over said first pole layer, said mask terminating adjacent to a desired location of said second side, and removing said mask to define said inorganic nonferromagnetic apex.
