Million Year Data Storage Disc is Debuted

Want to store your data for million years? Possible now. Most discs can store information for a decade or so. But now scientists are about to debut a special nanotechnology disc that has a million year storage capacity.

Want toData storage on discs began in the year 1956. It was then that IBM built the first computer that could save information in disc form. Today we have come a long way since those good old days. Over one terabyte of data can be stuffed into a single 3.5 inch disc. However, as they say the more things change, the less they change. The life of the disc is not more than ten odd years.

This was a limitation up until now. The quest to save the knowledge and wisdom of our civilization on a scale that would outlast its life span was an unreachable goal. Not anymore though! A research team in the Netherlands has come up with a disc that could save unlimited amounts of data for up to a million years.

The mechanics of the anti-aging formula used for this disc is very complex. It depends upon energy barriers and the Arrhenius Law. Lines are scratched on a very slim metallic disc which is then given a protective covering. The metal chosen as a base is tungsten which has a very high melting point. And the protective outer layer is made of silicon nitride which is quite fracture-resistant.

The fact that this disc will survive the man-made wars and ravages of nature is a very good sign. It means that future civilizations, even if they are bizarre compared to our own, can recognize some of the cultural capital found on the million year disc.
