Abstract :
Scanning-probe data-storage devices are currently being explored as alternatives to conventional data storage. Ultra-high density, small form factor, and low cost are thought to be the primary advantages of probe storage. The ultra-high a real density makes nanopositioning a significant challenge in probe storage. In this paper, we discuss the control of a MEMS scanner used in a probe storage device which uses thermo-mechanical means to store and retrieve information on thin polymer films. The MEMS scanner has X-Y motion capabilities with a travel range of approx 120 μm. Thermal position sensors are used to provide positioning information. This paper describes the dynamics of the micro-scanner, the primary control challenges, and the way they are addressed.
