| 20100092717 | OPTICAL RECORDING MEDIUM BASED ON A TELLURIUM AND ZINC ALLOY - The optical recording medium comprises an active layer made of inorganic material, presenting a front face for receiving an optical radiation during writing operations, and a rear face. The inorganic material is a tellurium and zinc alloy comprising an atomic percentage of between 60% and 70% of zinc and between 30% and 40% of tellurium. The alloy comprises preferably 65% of zinc and 35% of tellurium. The medium may comprise a semi-reflecting layer arranged on the front face of the active layer and/or an additional metal layer arranged on the rear face and/or a protective layer of polymer material on the rear face. Thus, writing powers, a mark resolution and a storage density corresponding to DVD format specifications may be achieved. | 04-15-2010 |
| 20080274323 | Process for Producing an Optical Recording Medium with Several Stages and Medium Obtained Thereby - The recording medium comprises at least a first (L | 11-06-2008 |
| 20080267048 | Irreversible Optical Recording Medium by Formation of Bubbles Having a Height Limited by the Gas Source Generating Them - 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. | 10-30-2008 |
| 20080260983 | Irreversible Optical Recording Medium Comprising A Track with Low Raised Zones And Method For Using Same - An irreversible optical recording medium comprises at least a substrate whereon is arranged at least a photosensitive layer comprising a structured front face destined to receive an optical radiation during data recording and/or reading operations. The medium also comprises a track comprising raised zones, having:
