  • Patent number: 6433949
    Abstract: A head for writing a plurality of bands. The bands have magnetic transitions onto a magnetic media (110). The magnetic media (110) travels in a preselected direction. The head includes a body support structure (100) and a plurality of write elements (120). The write elements (120) have a fixed alignment in the body support structure (100) that is substantially perpendicular relative to the travel direction of the magnetic media (110).

  • Patent number: 5479716
    Abstract: An improved inclination sensor in which electrically conductive elements are fabricated onto one or both surfaces of a flat plate. The plate comprising discrete, isolated sector sections having a distinct electrically conductive regions is oriented in a substantially vertical plane. The plate has an axis which lies in a horizontal plane and which is substantially perpendicular to the plate so that the plate may tilt about the axis. The plate is encased within a sealed chamber occupied by a fluid having electrical properties. In one embodiment a dielectric fluid occupies a first portion of a chamber and has a dielectric constant greater than that of a gas which occupies a second portion of the sealed chamber. The fluid flows in response to a change in the tilt of the sealed chamber and the plate. In a second embodiment a capacitive fluid changes the capacitance between the distinct electrically conductive regions of each section of the plate.
