Abstract

"DISCO óPTICO DE CAMADA DUPLA DE ALTA DENSIDADE". Um disco óptico de camada dupla de alta densidade da presente invenção é configurado de modo que a primeira espessura do substrato, da superfície de incidência de luz de um substrato transparente para a primeira camada de gravação, seja igual a um valor obtido por subtração de metade da distância entre as primeira e segunda camadas de gravação da espessura do substrato, da superfície de incidência de luz do substrato transparente para uma camada de gravação em um disco óptico de camada única de alta densidade genérico, e a segunda espessura do substrato, da superfície de incidência de luz para a segunda camada de gravação, é igual a um valor obtido por adição de metade da distância entre as duas camadas de gravação para a espessura do substrato, da superfície de incidência de luz para a camada de gravação em um disco óptico de camada única de alta densidade genérico.
