  • Magnetic head and process for making laminated magnetic head
    Patent number: 4149205
    Abstract: An improved integrated magnetic head structure of the type having a plurality of thin metal layers forming a magnetic head winding. These layers are generally symmetrical to a plane of symmetry lying perpendicularly to a gap plane on a non magnetic, insulating substrate, and these layers have flanks which are, with increasing distance from the substrate, shortened by a predetermined length distance. This head structure requires only a few masks to make with a minimum of mask adjustments. Extremely fine structures can be produced.
