Nanotechnology may be part of our newest generation of discs, giving them 2,000 times the storage space of a DVD and effectively making them five-dimensional.  Swinburne University of Technology’s Centre for Micro-Photonics created nanoscopic technology that was integrated into a disc and increased its storage capacity without increasing its actual size.

In addition to the three dimensions that discs currently have, the researchers added a spectral (color) dimension and a polarization dimension. his technology is still in its early stages.  There are several unresolved issues, such as the speed at which a disc can be copied, that the researchers say need to be worked out before the discs could ever be mass produced and reach the consumer market.  They do expect it to be available in five to ten years, and to be especially useful for military, medical and financial sectors.
