Femtosecond Laser Nanogratings Create “Five Dimensional” Storage

March 25, 2016

Scientists from the University of Southampton in the UK have created a new data format that encodes information in tiny nanostructures that are etched into glass discs. A standard-sized disc can store approximately 360 terabytes of data, with an estimated lifespan of up to 13.8 billion years.

This breakthrough is not only monumental for records keeping, but also for the optical industry as a whole. The “5D” storage technique has numerous benefits over film, CD’s and other storage medium which have multiple drawbacks.

The infographic below shows backup storage media’s expected lifecycle. As you can see the “5D” storage method could be light years ahead of any media storage technique we have ever used.
