Abstract
The present invention concerns a storage medium for scanning probe storage devices. This storage medium comprises a substrate (20) carrying a shape memory alloy layer (24). The shape memory alloy layer (24) is chosen such that an indent (23) can be formed by mechanically deforming said shape memory alloy layer (24), if a local probe (21, 22) of said scanning probe system exerts pressure on said alloy layer (24). An indent (23) can be removed by locally heating said shape memory alloy layer (24) to its transformation temperature (Tc) or above such that the shape memory alloy returns to its Martensite form.
