Beschreibung
Zusammenfassung:A method and apparatus for storing data is provided incorporating an amorphous solid having covalent bonds and a first index of refraction and an energy source for thermally heating selected areas of the amorphous solid to change the index of refraction without melting or substantially crystallizing the amorphous solid. The invention overcomes the problem of corrosion, moisture, or microbial attack resulting in deterioration of the storage medium over time, i.e., 100 years.
