  • Patent number: 7355955
    Abstract: A nanoscale digital data storage device is provided. In the nanoscale digital data storage device, a storage medium has a polymer layer deposited on a substrate, for writing and reading digital data on and from. A cantilever chip has a plurality of cantilevers arranged therein. Each cantilever is fixed to another substrate at one end and has a tip formed at its free end, for emitting heat according to an applied current. The tips in the cantilever chip are in contact with the storage medium at predetermined bit positions during data writing, and the cantilever chip applies a relatively low current to a tip when the tip writes bit 1 and a relatively high current to the tip when the tip writes bit 0.

  • Patent number: 4712208
    Abstract: Apparatus for reducing the effects of vertical perturbations of a phonograph disc surface resulting from disc and/or playback system mechanical imperfections. Such imperfections are compensated by closed loop and/or open loop means wherein the deviations of the record path are detected and employed to minimize the effects of the mechanical imperfections.
