We could soon store 700 Terabytes on a 12-centimeter optical disk which would be equal to storing 28,000 Blu-ray disks. A separate advance with in data encoding could triple storage to 2.1 Petabytes in a single optical disk. Researchers at USST, RMIT and NUS have overcome the optical diffraction limit by using earth-rich lanthanide-doped upconversion nanoparticles and graphene oxide flakes. This unique material platform enables low-power optical writing nanoscale information bits. The higher density system will use inexpensive continuous-wave lasers. This will have lower operating costs compared to traditional optical writing techniques using expensive and bulky pulsed lasers. Next generation
