ABSTRACT:
A perpendicular recording head for use with magnetic recording media includes an unusually thin main pole. The main pole is made by depositing magnetically permeable material on a nonmagnetic substrate. The main pole is then magnetically coupled with an opposing pole so that the deposited magnetically permeable material is oriented parallel to the recording head's direction of travel.
