Abstract

L'invention vise à supprimer un bruit dû à une lumière de fond en amenant la réflectance d'une région, autre qu'une ouverture dans un point de collecte de lumière, proche de zéro au moment de la reproduction d'informations, et vise à supprimer la détérioration d'un faisceau laser lui-même et d'un disque optique en raison d'une irradiation de faisceau laser haute intensité continue dans un système de reproduction à super résolution. A cet effet, un support d'enregistrement d'informations optique (10) est configuré par stratification d'une couche de film de correction de réflexion (17), qui est composée d'une pluralité de couches de film à super résolution, sur une surface creuse d'enregistrement d'un substrat transparent (11). La couche de film de correction de réflexion (17) est configurée de telle sorte que la réflectance à la lumière d'irradiation décroît en continu à mesure que la température augmente à partir de la température normale et augmente rapidement à une température de point de déplacement.
