Rewritable data storage using carbonaceous material and writing/reading method therof

摘要

A rewritable data storage using a carbonaceous material writes or erases information represented by the carbonaceous material (30) by means of a current induced electrochemical reaction on a conductive layer (20), by controlling a voltage applied across the space between cantilever tip (50) and the conductive layer. Also, the size of the carbonaceous material representing information is controlled by the level of the applied voltage or the application duration.
