Abstract

L'invention vise à proposer un support d'enregistrement d'informations optiques qui permet d'enregistrer à une vitesse supérieure même lorsque l'épaisseur d'une couche d'enregistrement d'une couche d'informations est réduite, et qui a une excellente productivité en masse. A cet effet, l'invention concerne un disque optique (10) pour enregistrer/reproduire des informations en amenant à varier la propriété optique d'une couche d'enregistrement (14) par irradiation par un faisceau laser. Le disque optique (10) est caractérisé par le fait qu'une couche protectrice d'oxyde Lox-Mox comprenant un mélange d'oxydes Lox et Mox est laminée sur les deuxsurfaces de la couche d'enregistrement (14) sous forme d'une première couche d'interface (1) et d'une seconde couche d'interface (15). L'oxyde Lox est un oxyde d'au moins un élément choisi parmi les éléments de la famille des lanthanides tels que Ce, Nd, Eu, Gd et Dy. L'oxyde Mox oxyde est un oxyde d'au moins un élément choisi parmi Si, Al et Ta.
