Computer memory stored on nano-structured glass discs

nanoglass

University of Southampton have created nano-structured glass discs that mean a whole new generation of computer memory. The millimetre-sized device changes the way light travels through glass, generating ‘whirlpools’ of light that can be read in much the same way as data in optical fibres, except the “whirlpools” of light data can be even more precise and allow for the optical manipulation of atom-sized objects.
