  • Patent number: 9336806
    Abstract: Tape head with thermal tape-head distance sensor to reduce the distance between the tape and the head to allow an increase in areal density. A tape head designed for reading and/or writing to a tape, including: a tape bearing surface shaped to form an air bearing when moving the tape with respect to the tape bearing surface; a thermal tape-head distance sensor circuit adapted to sense heat dissipated at the level of the tape bearing surface by the tape and thereby sense a distance between the tape bearing surface and the tape; and tape-head distance control means connected to the thermal tape-head distance sensor circuit to receive a signal provided by the tape-head distance sensor circuit and configured to alter the distance according to a signal received from the tape-head distance sensor circuit. This invention is further directed to a method of tape-head distance control for the above tape head.

  • Patent number: 9230564
    Abstract: In one general embodiment, a method is provided for fabricating magnetic structures using post-deposition tilting. A thin film magnetic transducer structure is formed on a substantially planar portion of a substrate such that a plane of deposition of the thin film transducer structure is substantially parallel to a plane of the substrate. Additionally, the thin film transducer structure is caused to tilt at an angle relative to the plane of the substrate. The thin film transducer is fixed at the angle after being tilted.
