Employees of the Department of Optoelectronics Research University of Southampton succeeded in developing an innovative method storage of digital data, allowing in theory to store giant volumes of information for an infinitely long time. As a thin disc made of transparent material will protrude the size of a five-ruble coin.
Unique technology called “Eternal 5D”, characterized by incredibly high data recording density, with this information, according to the inventors, will be safely stored for many billions of years. Given the fact that Christian era lasts just over two millennia, designed the British optical drive will have virtually unlimited lifetime. “Rather, humanity will die out than our drive will fail, “jokes Peter Kazan, one of the authors project.
The technology is based on the so-called femtosecond laser, recording data through ultrashort pulses to a disk from quartz glass. On a carrier with a diameter of two and a half centimeters can record up to three hundred and sixty terabytes information. According to the British, this is enough to to save all the useful text information created by our civilization. In 2013, when scientists were just beginning to master this technology, they were able to write to the drive maximum three hundred kilobytes of text.

Unique disc is able to survive the atomic war
At temperatures from minus one hundred to plus one hundred and ninety degrees Celsius such a storage medium can be stored almost fourteen billion years. Nanostructured Quartz Racks Not only to cooling and heating, but also to scratches, bumps and other methods of mechanical action. Peter Kazan says: “We created a technology that allows us to save for our descendants are huge amounts of information. The most important thing is that quartz disks are almost eternal and can, unlike any other modern drives, survive even an atomic war. ”
Data is written to disk once, and overwriting is not possible. Thus, create a quartz glass hard drive for a home computer will not work. However, developed Southampton University scientists will be able to technology use in archives, libraries, museums, educational institutions. IN currently the british are looking for investors willing to invest in development and commercialization of this innovation.
