CA 2232225

In a phase change optical recording medium in which writing, reading and/or erasing of information is conducted by utilizing change of phase of a recording layer by irradiation with light, the recording layer is made of a material containing oxygen in an amount of 1 to 30 atomic %; or the recording medium comprises an additional transparent dielectric layer 1 to 10 nm thick between the recording layer and the underlying transparent dielectric layer and the inserted transparent dielectric layer in contact with the recording layer comprising oxygen in a molar ratio greater than a molar ratio of oxygen in the underlying transparent dielectric layer; or the transparent dielectric layer underlying and in contact with the recording layer comprises oxygen in a molar ratio greater than a molar ratio of oxygen in the other transparent dielectric layer.

Dans un support d'enregistrement optique par changement de phase dans lequel l'écriture, la lecture et/ou l'élimination de l'information sont réalisés en recourant au changement de phase d'une couche d'enregistrement par irradiation avec la lumière, la couche d'enregistrement est composée d'une matière contenant entre 1 et 30 % en poids atomique d'oxygène; ou le support d'enregistrement comprend une couche diélectrique transparente additionnelle de 1 à 10 nm d'épaisseur entre la couche d'enregistrement et la couche diélectrique transparente sous-jacente et la couche diélectrique transparente insérée en contact avec la couche d'enregistrement comprenant de l'oxygène dans un rapport molaire supérieur au rapport molaire de l'oxygène dans la couche diélectrique transparente sous-jacente; ou la couche diélectrique transparente sous-jacente, en contact avec la couche d'enregistrement, comprend de l'oxygène dans un rapport molaire supérieur au rapport molaire de l'oxygène dans l'autre couche diélectrique transparente.
