Integrated magnetic recording heads applications

The purpose of this paper is to describe the technical advantages of integrated magnetic heads. This technology has been tested for use in two types of applications: magnetic tape and magnetic disk. Results relating to magnetic compatibility or "media compatibility," definition, high-density feasibility, frequency bandwidths, and wear are presented for the two types of applications tested. It has been found that integrated heads produce a field gradient that is determined by the geometrical form of the head tips. Moreover, the field gradient does not depend on the applied magnetomotive force, which permits the optimization of a head on any given medium. The manufacturing possibilities of these heads and their advantages over conventional heads are discussed.
