CONTROL SCHEME FOR A MEMORY DEVICE
First Claim
1. 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 trajectory generated by the trajectory generator based on a measurement of a position of the media relative to the tip.

Abstract
A system for storing information comprises a media die including a frame and a media platform movably coupled with the frame, a media associated with the media platform, one or more capacitive sensors including an electrode fixedly connected with the media platform, and 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. The system further comprises 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 trajectory generated by the trajectory generator based on a measurement from the one or more capacitive sensors.
