A group of researchers from the University of Southampton , know a new and interesting form of storage, consisting of five-dimensional nanostructures within a quartz crystal , thus bringing the possibility of having almost eternal form, an amount brutal information securely in a small disk.
The recording technique is based on small laser pulses of very short duration, we are talking fem to second, which generate a three-layer structure of nanostructured points separated by only 5 microns, equal to one millionth of a meter, which allows you to record up to 360 TB of information in a small quartz crystal five-dimensional nanoscopic level.
This structure offers a longevity never seen before, as researchers say the information could remain intact for 13,800 million years at a temperature of up to 190 ° C , although these small drives are able to withstand temperatures up to 1,000 ° C, something obviously it reduces its life, but the point is to show high storage capacity and durability that can provide a device of this type, which could be stored almost all knowledge of history and humanity for millions of years.
This technique is not new, in 2013 the first storage tests on quartz began and today we have works like the Universal Declaration of Human Rights, the Bible and the Constitution, all stored in these tiny glass discs, but achieving this time is the development and expansion of the structure , which will give the possibility to have a large storage capacity.
