Incorruptible Data

From Gizmag. Finally, there is a way to make sure your data is safe. Hitachi has developed an "incorruptible" glass-based data storage technique. It uses microscopic dots within a piece of quartz glass, the dots being binary data. The data should be stable for at least several hundred million years.

The current two-centimeter square, two millimeter thick prototype can contain about 40 megs of data. Researchers are confident they can increase storage by adding more layers.
