Abstract:
A method for forming a giant magneto-resistive head with a high data-rate stitched pole magnetic write head comprising:providing a giant magneto-resistive read head assembly having an upper magnetic shield which will serve as a lower pole piece for an inductive magnetic write head, upon which a write-gap layer has been deposited and planarized; depositing on said write-gap layer-a photoresist layer of thickness between 1.0 microns and 5.0 microns; exposing a first region of said photoresist layer; developing and removing said first region; depositing in said region a spacer layer of non-magnetic material; exposing a second region of said photoresist layer; developing and removing said second region; depositing a pole tip layer of magnetic material in said second region and over said spacer layer; depositing a pole yoke layer over said pole tip layer so that the front surfaces of the pole tip layer and the pole yoke layer are co-planar.
