Abstract

Disque optique (12) préenregistré à double couche comportant un sbstrat transparent (14), une couche partiellement réfléchissante (16), une couche d'espacement transparente (18) et une couche à haut pouvoir réfléchissant (20). Un motif de microcuvettes de données (15) est ménagé sur le substrat de manière contiguë à la couche partiellement réfléchissante, tandis qu'un autre motif de microcuvettes de données (19) est ménagé sur la couche d'espacement, de manière contiguë à la couche à haut pouvoir réfléchissant. La couche partiellement réfléchissante peut être constituée de carbure de silicium. Un faisceau incident sur le substrat peut être utilisé pour lire les données codées dans chacun des motifs de microcuvette de données, en fonction de la couche sur laquelle le laser (30) est focalisé. Ce disque à couche double présente une capacité de stockage de données double par rapport aux disques ordinaires à simple couche.
