Probe-based Data Storage Technology: Thermomechanical Storage –State of the Art

Abstract

Ultra high density data storage imposes an ever increasing demand on the capacity and speed of data storage systems becoming an essential issue in this digital age. Secondary storage has been indispensable constituent of any computer system for storing data at high speed with ultra-high density. AFM (Atomic Force Microscopy) based data storage is a promising alternative to conventional magnetic data storage because it offers great potential for considerable storage density improvements, which has become very popular. Significant challenges, salient features and associated benefits of the nano tip based data storage devices were discussed briefly in this case study. This study addresses the following: (i) a brief discussion on emerging research directions broadly in the areas of thermomechanical data storage and storage intersecting low-dimensional polymer materials; (ii) advancing experimental methods to fabricate microcantilever with nano tip that can sustain with pulse gradient, thermo mechanically stable under large thermal cycles which can be electrically interrogated with negligible parasitic loss.
