Superman crystal ‘can secure the last evidence of civilization’

Nanostructured glass could be the key to storing vast quantities of information on a single disc for more than a million years. A new technology uses a femtosecond laser to record digital text in 5-D via self-assembled nanostructures created in fused quartz. The five dimensions include size and orientation in addition to the 3-D coordinates of these nanostructures. The storage allows unprecedented parameters, including 360-TB/disc data capacity, thermal stability up to 1000 °C and an unlimited lifetime. The method’s developers at the University of Southampton and Eindhoven...Read full article

    Glossary
    fused quartz
    Crystal quartz that is melted at a white heat and cooled to form an amorphous glass. It is not birefringent and the refractive index is much lower than that of crystal quartz. Fused quartz of optical quality can be prepared by suitable techniques.
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    nanostructured glass
    A unique glass made up of nano-structured materials to create millimeter sized monolithic glass space-variant polarization converters which ultimately alter the way light propagates through and is ultimately stored in glass. This store and read technique allows for more precise laser material processing, ultra-high resolution imaging, as well as optical manipulation of atom-sized objects.
