Abstract

Abstract Translated from French L'invention se rapporte à l'inscripton thermo-optique d'information sur un support à couche métallique ductile (1) étirée au delà de la limite élastique par la poussée exercée par une couche contigüe (3) de substance organique thermo-deformante. L'invention a pour objet un support d'information dans lequel une couche métallique réfléchissante (2, 12) délimite avec la couche métallique ductile (1) perméable au rayonnement inscripteur, une cavité optique accordée à l'anti-réflexion. L'invention s'applique notamment à l'enregistrement et à l'archivage de l'information sous forme numérique. The invention relates to the thermo-optic information label on a support with a ductile metal layer (1) stretched beyond the elastic limit by the thrust exerted by a contiguous layer (3) of heat-deforming organic substance. The invention relates to an information medium in which a reflective metallic layer (2, 12) defines with the ductile metallic layer (1) permeable to the listing radiation, an optical cavity tuned to the anti-reflection. The invention applies in particular to the recording and archiving of information in digital form.
