A group of Australian scientists have come up with a way so that you can store almost 10TB of data on a single disc. The teams from Swinburne University of Technology, Australia, have successfully added “the dimensions of color and light polarization” to our already existing technology in DVDs giving it very big boost to its maximum storage capacity.
These new discs will be capable of storing 10TB data as compared to our recent DVDs. Currently they have manufactured only a disc which can store only 1.6TB of data and these could be on sale through Samsung within the next five years, as a deal has already been snatched. In addition to that, 10 TB will eventually be possible but we have to wait another 10 years.
According to the researchers announce that due to the color and polarization extra space is capable to record information.
The colors dimension is produced by using gold nanorods which form surface plasmons when hit by light. As the nanoparticles counter with light according to their shape and sizes, this allows the researchers to trace information in a variety of different colors and wavelengths on the same place on the disc. The current DVDs are recorded in a single color wavelength using a laser.
