5D digital data storage developed with nano glass can be stored for billions of years

scientists at Optoelectronics Research Centre (ORC) of University of Southampton, UK, have developed the recording and retrieval process of 5D digital data through femtosecond laser writing using nano glass

this storage has unprecedented performance, such as 360 TB data capacity, thermal stability up to 1000 ℃ and almost unlimited life at room temperature, which will create a new era of data archiving that will never be crushed. In modern society, the demand for the stability and security of portable memory is higher and higher. This technology will play an important role in organizations with large archives, such as national archives, museums and libraries, to protect information and records

in 2013, this passage was demonstrated for the first time with the engineering language generalization technology - successfully recording a digital copy of a 300 KB text file in the form of 5D

now, some important cultural treasures of human history can be preserved in digital copies. Recently, at the closing ceremony of the International Year of light (International Year of light (iyl) held in Mexico, ORC submitted the UDHR copy encoded into 5D data storage to UNESCO (UNESCO)

ultrafast laser (i.e. generating extremely short and strong pulses) can be used to record these files. Write the file into three layers of nano dots with 5 micron spacing

self assembled nanostructures change the light passing through the glass, change the polarization of the light, and then read it through a combination of optical microscope and polarizer similar to polar sunglasses

glass memory is like a "Superman memory crystal", which can be compared to a "memory crystal" used in Superman thin films. It records data through self-assembled nanostructures constructed in fused silica. Realize information coding in five dimensions, that is, add size and orientation to the three-dimensional direction of the nanostructure

orc Professor Peter kazansky said; "It is very exciting that we have developed a technology that can preserve documents and information for future generations. This technology can ensure that the last evidence of our civilization: all we have learned will not be forgotten."
