ABSTRACT:
A magnetic write head having a metal, non-magnetic write gap that extends only partially to the magnetic back gap, the remainder of the distance between the pole tip and the back gap being a magnetic material. The elimination of the seed layer reduces the amount of milling required to perform the desired notching needed to form a self aligned pedestal on the first pole and voids electrolytic corrosion of the back gap during plating.
