Abstract

L'invention concerne les appareils d'enregistrement d'informations. Elle se rapporte à un appareil qui comporte un disque qui porte un film déformable, et un faisceau lumineux modulé par l'information provoque une redistribution de la matière du film déformable, cette redistribution pouvant être lue optiquement. L'énergie nécessaire à cette redistribution est bien inferieure à l'énergie nécessaire à la volatilisation de la matière. Application aux appareils de conservation d'informations sous forme optique.The invention relates to information recording apparatus. It relates to an apparatus which comprises a disc which carries a deformable film, and a light beam modulated by the information causes a redistribution of the material of the deformable film, this redistribution being able to be read optically. The energy required for this redistribution is much lower than the energy required for the volatilization of matter. Application to apparatus for storing information in optical form.
