摘要： A tape recording head is provided comprising a multiple plane transducer row having a plurality of planes of transducer arrays fabricated on a substrate and which may be staggered or offset relative to one another in a direction perpendicular to the direction of linear motion of the recording tape over the recording head. The multiple plane recording head provides a significant advantage over a head having a single transducer plane by allowing simultaneous reading (or writing) of data tracks on a magnetic recording tape that are more closely spaced apart with respect to one another than the spacing of the read (or write) transducers in a single plane.

摘要： A filled-gap magnetic recording head is provided comprising a flat or cylindrical contour head having a row of magnetic transducers in a gap region disposed between a rowbar substrate and a closure. The gap region is intentionally recessed to have a predetermined recess profile below a tape support surface. An electrical insulation layer is deposited on the tape support surface and on the recess profile of the gap region. The insulation layer prevents electrical shorting between the magnetic transducers and other conductive elements in the gap due to accumulations of conductive debris from the magnetic recording tape. A method of making the filled-gap magnetic recording head by intentionally recessing the gap region, cleaning the recessed profile and depositing an insulator layer is provided.

摘要： A system and method for monitoring fly height between a magnetic recording medium and a transducing head. In a first exemplary embodiment, magnetic spacing change value is calculated using media noise on the recording medium (instead of prerecorded tones) to provide a broadband frequency distribution that results in improved Wallace equation accuracy. In a second exemplary embodiment, a magnetic spacing change value is acquired by any suitable method but is adjusted as necessary to reflect transducing head wear, thus providing a methodology for calculating changes in fly height by taking into account the signal loss that is attributable to wear. In this way, a basic understanding of the mechanism causing changes in magnetic spacing is achieved.
