Glass that stores data forever
Hitachi has managed to develop a new method of storing data on glass, supporting that the information stored in it can be preserved for hundreds of millions of years!
A high precision laser records data by “paving” binary code signs in a tiny quartz glass.
In order to read the data, an optical microscope is required which helps with reading the code and by the use of a computer the stored data is retrieved.
This solution can survive and maintain data in almost every disaster scenario, since the glass is fireproof. As proof of this Hitachi heated a sample for two hours at 1,000 degrees Celsius and the stored data was read successfully.
Of course, not everything is perfect about this … capacity should be considered a major issue, as in each glass dimension of 2.5 square centimeters only 40MB of data density can be saved corresponding to that of the classic disc CD.
