ABSTRACT:
Superconducting material improves the operating efficiency and reduces the operating power demand for a disk drive suitable for interchanging data with a magnetic or optic media. The arm containing the head is moved along a path by a balanced superconductor to magnetic field interface such as for radial positioning relative to a circular media and is maintained in constant spatial relation with respect to the media by advantageous application of superconductive layers and magnetic field sources. The superconductor environment also permits efficient bearing support for the media as well as accommodating superconductor motors for driving the media and the use of various circuit elements associated with the drive electronics.
