Long term data storage in photosensitive glass

DESCRIPTION

  • The invention relates to a new data storage method based on a photosensitive glass
  • It allows storage of information in three dimensions in a photosensitive glass. The fluorescence produced is controlled and stabilized at the nanoscale, allowing to handle the intensity and to adapt the emission spectrum.
  • Playback works by fluorescence with 256 grey levels, using Blue – Ray technology, with slight technical improvements.

APPLICATIONS

Projanus is a new process which can modify any conductive micro or nano-object, to an asymmetric and bifunctional micro or nano-object. The induced anisotropy in color, charge density or reflective index could open the way to cheap pixels with high refreshing rate.

Janus particles are used in numerous industries:

  • Micro and nanoelectronics,
  • Chemical catalysis
  • Stabilization of emulsions,
  • Therapeutic,
  • Medical imagery,
  • Photovoltaics…

 

BENEFITS

  • Capacity : 1 Terabytes (1To),
  • Perpetual Digital Data Storage: several hundreds of years,
  • High tolerance to temperature,
  • High reading speed (500 Mbps),
  • Ease of implementation of protection (DRM, Datamatrix).
