  • Method of making a magnetoresistive head with integrated bias and magnetic shield layer
    Patent number: 5312644
    Abstract: A thin-film magnetoresistive playback head having films providing magnetic shielding and magnetic bias. At least one of the magnetic shield layers is also conductive so that the functions of shielding and biasing are combined. Preferably, both shield layers are conductive. A multiple element channel head is disclosed in which the magnetic/conductive layers extend in series from one transducer section to the next, allowing a single bias current to bias all of the sections.
    Type: Grant
    Filed: September 17, 1993
    Date of Patent: May 17, 1994
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Theodore A. Schwarz, Peter G. Bischoff, Chak M. Leung, Johnny C. Chen, Pradeep Thayamballi
