Abstract:
A method of making a magnetic write head having a yoke region that is located between a pole tip region and a back gap region comprising the steps of:forming a ferromagnetic first pole piece layer in the pole tip, yoke and back gap regions;forming at least a portion of a nonmagnetic nonconductive write gap layer on the first pole piece layer in the pole tip region;forming a ferromagnetic second pole tip portion on the write gap layer in the pole tip region with a top and first and second side walls;forming a nonmagnetic nonconductive protective insulation layer on the top and first and second side walls of the second pole tip portion; andsubsequent to forming the protective insulation layer forming metallic components of the write head with the protective insulation layer on said top and said first and second side walls of the second pole tip portion.
