MessageToEagle.com – Scientists have made a major breakthrough in the development of digital data storage that is capable of surviving for billions of years. With help of this cutting-edge technology we will now be able to preserve the records of our history and planet for billions of years. The technology will simply secure the last evidence of our civilization.
Using nanostructured glass scientists from the Southampton University have developed the recording and retrieval processes of five dimensional (5D) digital data by femtosecond laser writing.
The storage allows unprecedented properties including 360 TB/disc data capacity, thermal stability up to 1,000°C and virtually unlimited lifetime at room temperature (13.8 billion years at 190°C ) opening a new era of eternal data archiving. As a very stable and safe form of portable memory, the technology could be highly useful for organisations with big archives, such as national archives, museums and libraries, to preserve their information and records.
This technology was presented for the first time in 2013 when a 300 kb digital copy of a text file was successfully recorded in 5D.
Eternal 5D data storage is of vital importance to anyone interested in preserving the knowledge of our civilization.
Major documents from human history such as Universal Declaration of Human Rights (UDHR), Newton’s Opticks, Magna Carta and Kings James Bible, have been saved as digital copies that could survive the human race. A copy of the UDHR encoded to 5D data storage was recently presented to UNESCO by the ORC at the International Year of Light (IYL) closing ceremony in Mexico.
The documents were recorded using ultrafast laser, producing extremely short and intense pulses of light. The file is written in three layers of nanostructured dots separated by five micrometres (one millionth of a metre).
The self-assembled nanostructures change the way light travels through glass, modifying polarisation of light that can then be read by combination of optical microscope and a polariser, similar to that found in Polaroid sunglasses.

Coined as the ‘Superman memory crystal’, as the glass memory has been compared to the “memory crystals” used in the Superman films, the data is recorded via self-assembled nanostructures created in fused quartz. The information encoding is realised in five dimensions: the size and orientation in addition to the three dimensional position of these nanostructures.
“It is thrilling to think that we have created the technology to preserve documents and information and store it in space for future generations. This technology can secure the last evidence of our civilization: all we’ve learnt will not be forgotten,” Professor Peter Kazansky from the University’s Optoelectronics Research Centre (ORC) said.
