MULTI-LAYERED PHOTOCHROMIC OPTICAL DATA DISK

A 2.5-dimensional optical storage medium (101) is formed from multiple layers of photochromic molecules embedded in a polymer matrix separated by transparent separating layers (107). The medium (101) is moved into position in three dimensions for two-photon single beam information writing. The infor...

Abstract A 2.5-dimensional optical storage medium (101) is formed from multiple layers of photochromic molecules embedded in a polymer matrix separated by transparent separating layers (107). The medium (101) is moved into position in three dimensions for two-photon single beam information writing. The information thus written can be read bit-by-bit or page-by-page. In the latter case, an area is illuminated, and the fluorescence is detected by a CCD camera. L'invention concerne un support (101) de mémorisation optique de dimension 2 1/2 formé de couches multiples de molécules photochromes insérées dans une matrice polymère, ces couches étant séparées par de couches (107) de séparation transparentes. La position du support (101) est réglée en trois dimensions pour permettre une écriture d'information par faisceau unique à deux photons. L'information ainsi écrite peut être lue bit-à-bit ou page par page. Dans ce dernier cas une zone est illuminée et la fluorescence est détectée par une caméra à couplage de charge.
