Long term data storage in photosensitive glass
- 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.

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,
- Medical imagery,
- 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).
