  • Shielded magnetoresistive magnetic transducer
    Patent number: 3940797
    Abstract: A magnetoresistive (MR) layer is placed offcenter the distance between two shields to enhance self-biasing. Information is carried on a magnetizable medium as recorded magnetic areas. The shields are spaced apart by a distance on the order of and less than the shortest recorded wavelength for which the head is meant to be used. The MR element and the shields have their edges nearest the medium in a common plane perpendicular to the vertical component of a signal from the recorded area. An additional shunt bias layer may be provided immediately adjacent and coextensive the MR element, and the head may serve one or many tracks.
