US researchers come up with 2 TB optical disk


A professor and his graduate student at the Western Reserve University in the United States have created a new type of optical media that can store 2 TB of data.

Current optical discs boast capacities of up to 25 GB so the discovery is a huge leap ahead.

Apart from the huge storage capacity the disc will look like any other optical disc because it will be made from the same plastic material. The new invention however depends on 64 data layers that can store information – as comparison current optical discs make use of 2 layers only. Finally the new disk will require companies to only make slight changes to existing optical drives to make them compatible with the new disk format.

Sadly, there’s no word on the market appearance of the new technology – in any case we are looking at least at a few years.
