Eternal 5D Optical data storage could record the human race info for future
Eternal 5D Optical data storage could record the human race info for future for sure. It is a five-dimensional glass disc with size of an eye lens. Scientists at the University of Southampton founded this 5D Optical Storage drive in late 2016.
As we all know that there is no such device in this world which can store data for humans for lifetimes or for millions of years. Researchers at the University of Southampton founded a 5D nanostructured glass disc which can be used to store as well as retrieve data. It can store up to 360TB’s of data and can remain harmless protecting data even at the temperatures of 1000 Celcius. So practically it can store data safely for about 13.8 billion years if we consider it is kept at a temperature of 190 Celcius for its lifetime. It uses ultra fast laser technology to record data into glass disc. The data is written in three layers of nanostructured dots separated by a distance of five micrometres.he 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.
It uses ultra fast laser technology to record data into glass disc. The data is stored by self-assembled nanostructure created in fused quartz. The data is written in three layers of nanostructured dots separated by a distance of five micrometres. The self-assembled nano structure changes the properties of light passing through the glass, altering polarisation of light which can then further be read by the combination of an optical microscope and a polarizer, Just as found in Polaroid sunglasses. The data encoding is used in five dimensions: the orientation and the size in addition to the rest three dimensional position on which nanostructure works.
