    Abstract: A memory apparatus comprises a media, a tip adapted to write information to and read information from said media, a media movement mechanism attached to said media and configured to move said media in response to media control signals, and a capacitive sensor configured to detect an amount of relative movement of said media and said tip in at least an x-axis direction. The capacitive sensor includes a fixed comb having fingers protruding in an x-axis direction, a moving comb connected having fingers protruding in an x-axis direction, and an electrical path connected to said fixed comb and an electrical path connected to said moving comb. The relative movement in at least the x-axis direction is determined at least in part on a change in capacitance between said fixed and moving combs of said capacitive sensor.

    Abstract: A memory device whose media scanning is vibrationally (cyclic harmonic vibration) or inertially (one-time pulsed read/write) driven is provided, comprising a plurality of cantilevers (7, 7', 7"), attached at one end and capable of vibrating. On the opposite end of each cantilever is disposed an array of storage bits (26). Opposite the surface of each cantilever having such a bit array is a read/write head (27) which is similar in nature to a scanning tunneling microscopy or atomic force microscopy scanning-tip. Electronic support circuitry is provided to implement the memory device of the invention. Such circuitry includes a microprocessor (67), a multiplexer/demultiplexer (70), a group of circuits (66) comprising power supplies, sensing circuits and digital/analog and analog/digital conversion circuits, and switching means (65) to permit all of the previous functions to be properly addressed to/from the correct bit/array(s) and mating subdevice(s).

    Abstract: The invention in one embodiment thereof employs separate and respective heads for disparate signal frequency bands. One head is kept in intimate contact with the recording medium to maximize the response to the higher frequency signal band; and the other head is vibrated relative to the surface of the recording medium, thereby to augment(d.phi./dt)and to improve the playback response to the lower frequency signal band. Since the two heads cannot reside physically at the same location, a suitable delay device is employed to bring the signals from the two heads into proper timed relationship, the outputs of the two heads being appropriately band-passed to reconstruct a complex signal composed of the two signal bands.
