Using nanostructured glass, scientists at the University of Southampton have, for the first time, experimentally demonstrated the recording and retrieval processes of five dimensional digital data by femtosecond laser writing. The storage allows unprecedented parameters including 360TB/disc data capacity, thermal stability up to 1000°C and practically unlimited lifetime.

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, which is able to store vast quantities of data for over a million years. The information encoding is realised in five dimensions: the size and orientation in addition to the three dimensional position of these nanostructures.

A 300 kb digital copy of a text file was successfully recorded in 5D 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. The research is led by Jingyu Zhang from the University’s Optoelectronics Research Centre (ORC) and conducted under a joint project with Eindhoven University of Technology.

“We are developing a very stable and safe form of portable memory using glass, which could be highly useful for organisations with big archives. At the moment companies have to back up their archives every five to ten years because hard-drive memory has a relatively short lifespan. Museums who want to preserve information or places like the national archives where they have huge numbers of documents, would really benefit,” said Mr. Jingyu.

The Physical Optics group from the ORC presented their ground-breaking paper at the photonics industry's renowned Conference on Lasers and Electro-Optics (CLEO’13) in San Jose. The paper, ‘5D Data Storage by Ultrafast Laser Nanostructuring in Glass’ was presented by the during CLEO's prestigious post deadline session.

“It is thrilling to think that we have created the first document which will likely survive the human race. This technology can secure the last evidence of civilisation: all we’ve learnt will not be forgotten,” said professor Peter Kazansky, the ORC’s group supervisor.

The team are now looking for industry partners to commercialise this ground-breaking new technology.

I thought there are 4 known dimensions only. Now I found out there are 5. Time to rewrite all the physics books out there.

Sounds like the glass memory walls as seen in the Archival Building in the movie "The Time Machine".
Now they just have to synthesize voice into the layers and it will be complete.

Wow! Now we have the crystal memory chips
