Abstract

Moyen d'enregistrement destiné à être utilisé avec un faisceau laser d'enregistrement, fournissant une lumière d'une fréquence donnée, ce moyen d'enregistrement comportant une couche réfléchissant la lumière sur laquelle est déposée une couche absorbant la lumière, elle-même revêtue d'une couche supplémentaire, ce moyen étant caractérisé en ce qu'il comporte une couche barrière chimique et thermique, positionnée entre la couche absorbant la lumière et la couche supplémentaire, et en ce que l'épaisseur de cette couche barrière est une fonction de la longueur d'onde de la lumière émise par le laser d'enregistrement et de l'indice de réfraction de cette couche barrière, pour ladite longueur d'onde.
