Abstract: The poles are suited for mounting on the side of a slider carrying a magnetic head. The method allows very narrow gaps between poles. In one embodiment of the invention, a magnetic pole is deposited on a substrate. A nonmagnetic material such as Al.sub.2 O.sub.3 is deposited from the side onto the pole and substrate. A preselected pattern of photoresist is next deposited on the nonmagnetic layer and a second magnetic material is deposited. The photoresist is removed and excess magnetic material is removed by ion milling from the side opposite to that of the nonmagnetic material deposition. Another embodiment is disclosed for making two- and three-pole heads.

Abstract: The present technique involves the procedure of depositing magnetic material onto a substrate while subjecting the magnetic material, as it is deposited onto the substrate, to a magnetic bias field whose Oersted value is sufficient to substantially saturate the surface of the magnetic material in order to induce a state of uniaxial anisotropy.
