Wow! I'll soon be able to die and rest in peace, I'll finally be able to archive all the roms and video game history.

An incredible 5D hard drive capable of storing data for billions of years

A 5D hard disk in the form of a nanostructured quartz was developed by researchers at the University of Southampton. They claim that their system is capable of storing considerable amounts of data for billions of years.
A team of scientists at the University of Southampton in Britain is revolutionizing data storage systems completely. His project, conducted within the Optoelectronics Research Center, has resulted in the development of a hard disk that can stand the test of time.
According to its inventors, the device could last 13.8 billion years. An incredible technological performance that could solve a number of problems currently related to file storage devices, not viable in time.
The new generation hard disk comes in the form of a nanostructured quartz the size of a coin. Its secret in terms of resistance lies in an innovative method of writing and reading in 5 dimensions (5D). The latter theorized in 2013 has now become a reality.
It consists in burning the disc in a similar way to that of a classic CD. At the latter, the data transferred for storage is written by an engraving laser on one side.
2D Reading vs. 5D Reading
The data are then presented in the form of a binary system composed of a succession of 1 and 0 represented by plates and hollows. During playback, a light beam travels through the suite and interprets it to retranscribe the files. This is called two-dimensional writing and reading.
On the new disk, on the other hand, the information is encoded in 5 dimensions using self-assembled nanostructures in quartz fused by ultrafast lasers. The reading is then done with an optical microscope and a polarizer.
During this phase, five types of information are transcribed by the orientation of the nanostructures, their position, or the reflected light intensity. The result is a much more complex language.
More storage for more resistance
The advantage of this system is twofold: not only it can store much more data (up to 350 terabytes, or 350,000 billion bytes, according to researchers), but it also frees itself from CD vulnerability problems.
With this new technology, data is no longer recorded on the surface but inside the glass disc. The structure thus protects them from a number of environmental factors, making their long-term preservation possible. According to the researchers, the 5D disc would present a thermal stability at more than 1.000°C.
In other words, the device is extremely resistant. It has already been tested to record important documents such as the Universal Declaration of Human Rights, Isaac Newton's Optical Treaty and the King James Bible.
"The last proof of our civilization"
According to the scientists behind the project, this new storage method could considerably improve archiving methods. From now on, the latter hope soon to arrive at a marketable version.
Peter Kazan, one of the team members explains: "It is incredible to think that we have created technology that can preserve documents and information and store them in space for future generations. He concludes: "This technology can ensure the last proof of our civilization: all that we have learned will not be forgotten."
