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 molecular memory media having a media surface and a platform with read/write heads. The platform and media are moved to allow one of addition, removal, and repositioning of atoms, electrons, and charges on a surface of the media. The media is a material capable of storing data written to it, and detectable using a vibrating tip sensor that resonates at a free space value which is phase shifted when charges or anomalies on a surface of the media are present. Other methods of reading and writing to the media are presented. The media may be enhanced by augmenting grain boundaries of the media vis deposition and removal of PMMA materials. Servo trenches and sync bits identify positions of the read/write heads and maintain alignment during memory operations.
