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.
