Control scheme for a memory device

A method of positioning a media relative to a tip in a probe storage system including circuitry with a coarse tracking loop to provide motion signals to urge the media relative to the tip, wherein the media includes an electrode of a capacitive sensor, the method comprising:

• generating a trajectory for the media to be urged;
• urging the media based on the trajectory;
• receiving position information from the capacitive sensor;
• and
• adjusting a position of the media using the position information.

A system of storing information comprising:

• a media movable relative to a tip;
• a tip arrangeable in communicative proximity to the media
• wherein the media is movable relative to the tip;
• a capacitive sensor including an electrode fixed in position relative to the media and an electrode fixed in position relative to the tip;
• circuitry to provide a signal to urge the media relative to the tip the circuitry including a coarse tracking loop;
• wherein the coarse tracking loop includes a feed forward signal generated based on an initial position and a final position of the media relative to the tip and corrective signal based on a measurement of the capacitive sensor.

A system for storing information comprising:

• a media;
• a tip platform including a tip, the tip platform positioned relative to the media platform such that the tip is arrangeable in communicative proximity to the media;
• and
• circuitry to provide motion signals to urge the media platform relative to the tip platform, the circuitry including a coarse tracking loop;
• wherein the coarse tracking loop includes a trajectory generator and a primary control loop to adjust a generated by the trajectory generator based on a measurement of a position of the media relative to the tip.
