SUPPORT D'ENREGISTREMENT OPTIQUE IRREVERSIBLE PAR FORMATION DE BULLES AYANT UNE HAUTEUR LIMITEE PAR LA SOURCE DE GAZ LES GENERANT |
摘要 |
<p>An irreversible optical recording medium comprises at least an active layer presenting a rear face and a front face designed to receive at least an optical writing radiation. The optical writing radiation enables gas bubbles forming write marks to be formed locally in said active layer by means of a layer forming a gas source arranged on the rear face of the active layer. The layer forming the gas source moreover has a thickness less than or equal to 100 nm so as to limit the height of the bubbles formed in the active layer and therefore to improve tracking when read operations are performed. The layer forming the gas source is preferably made of carbon-doped hydrogenated amorphous silicon oxide.</p> |
