(FR) SUPPORT DE STOCKAGE OPTIQUE
Abrégé
(EN)
An optical storage medium comprising a storage layer (4) and a first layer (5) covering the storage layer (4). The first layer (5) provides optical properties sufficient for data retrieval from the storage layer using a laser (8) with a first wavelength WI, A second layer covers the first layer (5) and provides optical properties sufficient for data retrieval from the storage layer using a laser with a second wavelength W2.
(FR)
Support de stockage optique comportant une couche mémoire (4) et une première couche (5) recouvrant cette dernière. Ladite première couche (5) présente des propriétés optiques convenant à l'extraction de données de la couche mémoire au moyen d'un laser (8) présentant une première longueur d'onde W1. Une deuxième couche, recouvrant la première (5), présente des propriétés optiques convenant à l'extraction de données de la couche mémoire au moyen d'un laser opérant à une deuxième longueur d'onde W2.
