360TB 'Superman memory crystal' has a 'virtually unlimited' lifetime
February 17, 2016 - Uncategorized
Scientists at the University of Southampton are offering a tantalizing look into a new type of technology that could be be the future of data storage.
The new technology, dubbed “Superman memory crystal,” uses lasers and nanostructures to record huge amounts of data onto tiny glass disks. The research, which is being presented at a conference in San Francisco this week, could allow people to preserve data and documents for billions of years, scientists say.
The researchers have been experimenting with the technology, called 5-dimensional data storage, since 2013 when they first used the technique to record 300KB of text. Now, the technology has progressed enough that scientists are able to store up to 360TB of data on the disks. The “5D” technology uses a combination of lasers and tiny nanostructures to record the data, which can be viewed with an optical microscope and a polarizer
Perhaps the most intriguing part of the technology is that its creators promise the disks will have a “virtually unlimited” lifetime, if stored at room temperature (they estimate the disks will survive up to 13.8 billion years at 190 degrees Celsius.) Read more…
