  • Patent number: 6078479
    Abstract: A thin film read-write magnetic head useful in a tape apparatus includes a magnetic circuit consisting of two thin film magnetic layers which form a magnetic yoke that is divided into three closely spaced sections, the central section of at least one of the magnetic layers containing an interspace in which a flux sensing element, such as a magnetoresistive device or Hall effect device, is located. The three section yoke forms a continuous magnetic circuit, except for the transducing gap, which circuit consists of three sections corresponding to the three sections of the yoke. The total gap width determines the width of the data track being recorded. During the write mode, a magnetic valve including an electrical conductor provides a shunt path to bypass the flux sensing means so that all three sections of the head operate for recording.

  • Patent number: 5923505
    Abstract: A magnetoresistive (MR) read sensor fabricated on a substrate comprises an MR layer of magnetoresistive material, a soft adjacent layer (SAL) of soft magnetic material, and a manganese-based metallic antiferromagnetic (AFM) layer between the MR layer and the SAL layer. The AFM layer is in direct contact with the SAL layer and is separated from the MR layer by a non-magnetic spacer layer. A non-magnetic texturing layer is disposed between the SAL layer and the substrate. This structure exhibits a much larger pinning field than read sensors using oxide-based antiferromagnets.
