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.

Non volotaile storage media

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 Al2SO3, SiO2, Si, and
Sapphire.
