Abstract
A rewritable data storage using a carbonaceous material writes or erases information represented by the carbonaceous material by means of a current induced electrochemical reaction on a conductive layer, by controlling a voltage applied across the space between a cantilever tip 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.
