Title (EN) OPTICAL DATA STORAGE MEDIA CONTAINING AN ENCAPSULATED DATA LAYER
(FR) SUPPORT OPTIQUE DE STOCKAGE DE DONNÉES CONTENANT UNE COUCHE DE DONNÉES ENCAPSULÉE
Abstract:
(EN) Optical information media containing encapsulated data layers are disclosed. Selective layering of materials in inner radial, middle radial, and outer radial zones allows for the faces and edges of at least the data layers to be encapsulated by other materials, resulting in increased resistance to harmful environmental agents such as oxygen and moisture.
(FR) L'invention porte sur des supports d'informations optiques contenant des couches de données encapsulées. Une stratification sélective de matériaux dans des zones radiale interne, radiale médiane et radiale externe permet aux faces et bords au moins des couches de données d'être encapsulées par d'autres matériaux, conduisant à une résistance accrue à des agents environnementaux nuisibles tels que l'oxygène et l'humidité.
