  • Process for manufacturing a recordable optical disk, optical disk and rewritable layer obtained by the process
    Patent number: 7288305
    Abstract: A process for manufacturing a recordable optical disk including forming a back rewritable layer and depositing a transparent intercalary layer on the back rewritable layer, and forming a front rewritable layer including a metallic alloy and a cermet dielectric such that the front rewritable layer has a transmission rate greater than or equal to about 45%, and a recordable optical disk including a substrate and an active layer including a cermet, wherein the active layer covers at least one back rewritable layer and the active cermet layer has a transmission rate greater than or equal to about 45%.
    Type: Grant
    Filed: May 16, 2005
    Date of Patent: October 30, 2007
    Assignees: Commissariat a l'Energie Atomique

  • Irreversible optical recording medium
    Patent number: 7181753
    Abstract: The medium comprises a bilayer stack constituted of an inorganic layer (30) and a semi-reflecting layer (32). The inorganic layer (30) can be deformed under the effect of light radiation (34) passed through the semi-reflecting layer, which lowers the reflection coefficient of the stack. Application to irreversible recording of information data, for example on discs.

  • Laser beam optical recording medium featuring several read/write levels
    Patent number: 6746746
    Abstract: The inventions relates to a laser beam optical recording medium which features several read/write levels, comprising a first half-transparent level and at least a second level, the first one being close to the laser transmitting source, each level comprising a phase changing material layer with two stable states controlled by a laser beam, where the phase changing material is a metallic alloy whose chemical formula writes as: [(GeyTe1-y)a(SbzTe1-z)1-a]1-b(In1-xTex)b with: 0.4≦y≦0.6 0.3≦z≦0.5 0.4≦x≦0.6 0.3≦a≦0.5 0.01≦b≦0.3 the reflection coefficient of the first level being in the range from 10% to 30%, the transmission coefficient being at least 45%, the writing power being lower than 23 mW and the erasing power being lower than 10 mW.
