Abstract: A giant magneto-resistive (GMR) transducer for reading data signals magnetically recorded on tape includes a GMR sensor and a separation structure formed on a front edge of the GMR sensor. The GMR sensor reads data signals magnetically recorded on a tape located at a head-tape interface. The separation structure physically separates the GMR sensor from the head-tape interface. The separation structure includes at least one film formed of at least one of non-magnetic and ferromagnetic materials such that the separation structure isolates the GMR sensor from physical contact with the tape at the head-tape interface while maintaining the ability of the GMR sensor to read data signals magnetically recorded on the tape even though the GMR sensor is physically separated from the tape at the head-tape interface. The separation structure may include an under-layer film and an isolation film. The GMR transducer is fabricated by a series of fabrication steps.

Abstract: A thin film magnetic head having one or more magneto-resistive (MR) elements. A thermally conductive stud is incorporated in an underlayer of the head, below the bottom shield of the MR element. This stud acts as a heat sink, and enhances the heat flow from the bottom shield to the substrate to thereby reduce thermal contact noise in the device, as well as allowing use of higher bias currents when reading signals from the media.

Abstract: A method for stabilizing magnetic domains in dual stripe magnetic read heads is provided. This method first comprises providing a plurality of coupled magneto-resistive read elements in a spaced relationship. These read elements include top and bottom patterned magnetic shields on ceramic substrates, with two magneto-resistive (MR) sensor elements between the shields, all separated by insulating layers. Magnetic support structures are provided adjacent and separated from the coupled read elements, wherein the magnetic support structures provide a uniform magnetic field that stabilizes the magnetic domains of the MR sensors in the coupled read elements.
