Abstract: front page image
(EN)Provided is an optical recording medium which uses no substance to be regulated by the PRTR law, can be used also in an optical recording device using a blue laser and is environmentally friendly. An optical recording medium, characterized in that it has a reflection film layer comprising, as a main component, an aluminum composition containing aluminum or an aluminum alloy and a metal oxide of a metal except aluminum, and, formed so as to contact with the above reflection film layer, a dielectric protective layer comprising, as a main component, a niobium composition containing silicon dioxide or titanium dioxide and niobium nitride oxide.
(FR)L’invention concerne un support d’enregistrement optique n’utilisant aucune substance devant être régulée par la loi PRTR, que l’on peut employer dans un dispositif d’enregistrement optique avec un laser bleu, et étant inoffensif pour l’environnement. Elle concerne également un support d’enregistrement optique, caractérisé en ce qu’il possède une couche de film réfléchissant comprenant, comme composant principal, une composition d’aluminium contenant de l’aluminium ou un alliage d’aluminium et un oxyde de métal autre que l’aluminium, et, formée de manière à toucher la couche de film réfléchissant ci-dessus, une couche de protection diélectrique comprenant, comme composant principal, une composition de niobium contenant du dioxyde de silicium ou dioxyde de titane et de l’oxyde de nitrure de niobium.
(JA) 本発明は、PRTR法の規制対象物質を用いること等がなく、青色レーザを用いた光記録装置にも使用可能な、環境面に配慮した光記録媒体を提供することを主目的としている。  上記目的を達成するために、本発明は、アルミニウムまたはアルミニウム合金と、アルミニウム以外の金属の金属酸化物とを含むアルミ組成物を主成分として含有する反射膜層、および前記反射膜層と接するように形成され、二酸化ケイ素または二酸化チタンと、ニオブ窒化酸化物とを含むニオブ組成物を主成分として含有する誘電体保護層を有することを特徴とする光記録媒体を提供する。
