  • Patent number: 7570457
    Abstract: A magnetic recording head is provided comprising a flat contour head having a deposited closure. An ion-milled trench or recess is provided near the substrate edge to create a lip or wear zone between the trench edge and the substrate/gap interface. As the tape passes over the head, the lip begins to wear and acquires a bevel. After up to a few hundred hours of runtime, the bevel spans the entire length of the lip after which the bevel length remains constant resulting in a constant rate of head wear. The width of the lip or wear zone is chosen such that head wear chases gap and transducer wear resulting in reduced recession of the transducer from the recording tape.

  • Patent number: 7551393
    Abstract: 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.

  • Publication number: 20090133468
    Abstract: A wear gauge is provided for simulating the wear of a magnetic recording component at its interface with a magnetic storage medium comprising a wear gauge block having a wear surface that substantially approximates the geometrical dimensions and contour of the working surface of the magnetic recording component, wherein the wear surface has a coating of transparent material. A test method comprises mounting the wear gauge in a test fixture, positioning a tape and adjusting the over wrap angle at edges of the wear surface, choosing the desired tape tension, speed and runtime, and running the tape, preferably unidirectionally, in operational contact with the wear surface for the desired runtime. The wear surface is inspected under white light illumination to observe and record locations of interferometric color changes on the wear surface. The color changes are correlated to thickness changes of the transparent coating on the wear surface.
