London: “Five-dimensional” discs with a capacity 10,000 times greater than current DVDs could be on the market within 10 years, making it possible to pack more than 2,000 movies onto a single disc, researchers have reported.
A team from Swinburne University of Technology in Australia said by harnessing nanoparticles and a “polarization” dimension to existing technology, storage can be massively boosted without changing the size of a disc.
The researchers, who have signed a deal with Samsung Electronics, said the technique had allowed them to store 1.6 terabytes of data on a disc with the potential to one day store up to 10 terabytes. One terabyte would be enough to hold 300 feature length films or 250,000 songs.
“We were able to show how nanostructured material can be incorporated onto a disc in order to increase data capacity, without increasing the size of the disc,” Min Gu, who worked on the research, said. “These extra dimensions are the key to creating ultra-high capacity discs.” Discs currently have three spatial dimensions but using nanoparticles the experts were able to introduce a spectral or color dimension as well as a polarization dimension.
