摘要： 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.

摘要： A tape head assembly for writing data to and reading data from a tape includes a tape head member having an engagement surface that is configured to engage the tape as the tape moves past the tape head member. A plurality of arrays of interactive elements are supported on the engagement surface. Each array is longitudinally offset from each other array. Each individual array includes a read group having only read elements and a write group having only write elements. Each read group is laterally offset from each write group within each array.
