Abstract

It is still possible to read drawings and writings made in stone by ancient civilizations. However, more recent data storage media, such as magnetic storage media, are less reliable for very long term data storage because they deteriorate or are susceptible to external influences such as magnetic field, nuclear radiation, and heat. Accordingly, there is a danger that data that may be regarded as historically significant in future years may be lost. Disclosed herein is a possible solution to the problem of very long term data storage based on local probe array storage technology. The data storage media described herein are substantially immune to the adverse effects of fire, heat, magnetization, corrosion, nuclear radiation and the like. The solution contemplates writing data on a conventional, relatively soft storage surface such as PMMA and then transforming the soft material to a relatively hard and inert material by chemical processing, for example. Other materials for such long term data storage include Al 2 SO 3 , SiO 2 , Si, and Sapphire. 1
