Abstract:
Storage medium for use in a scanning probe storage system comprising a substrate (20; 30; 40 50) carrying a shape memory alloy layer (24; 34; 44; 54.x), wherein said shape memory alloy layer is covered by a mono-layer of molecules serving as a lubricant reducing friction between a local probe and the storage medium, said storage medium characterized in that said shape memory alloy layer (24; 34; 44; 54.x) is chosen suchan incident (23; 33) is formed by mechanically deforming said shape memory alloy (24; 34; 44; 54.x) when a local probe of a scanning probe system exerts pressure on said shape memory alloy layer (24; 34; 44; 54.x); andan indent (22; 33) is removed by locally heating said shape memory alloy layer (24; 34; 44; 54.x) to its transformation temperature (Tc) or above.
