While most discs can hold about 5GB data now, researchers from the Swinburne University of Technology in Melbourne, Australia have created five dimensional discs that can hold 2,000 times that amount. The team created the 10TB disc with a color dimension that uses nanoparticles that react to light according to shape, so that information can be recorded on different wavelengths. Polarization was also applied for recording layers of data. While there are still issues to work out, they foresee the discs in the market in the next 5 to 10 years. That will give us all time to save up the money to buy that much data in one disc.
