Abstract
Cette invention concerne un procédé de stockage de données selon lequel on utilise un support de données effaçable, de haute densité (7), possédant une couche intermédiaire d'oxyde métallique capable de subir une modification chimique optiquement lisible quand elle est exposée simultanément à la chaleur et à la lumière d'une longueur d'onde donnée. On obtient une image optiquement lisible dans les régions sélectionnées de la couche d'oxyde, dans les conditions ambiantes y compris O2, en exposant la couche simultanément à la chaleur et à un rayonnement situé dans le spectre bleu-vert ou de longueur d'onde inférieure. On efface l'image en chauffant le support entier au moyen d'un four ou en chauffant des parties sélectionnées grâce à un rayonnement infra-rouge.
