    摘要： An optical information recording medium including a first and second information layers is provided with an area where only the first information layer, which is provided nearer a substrate, exists, and initialization using a laser beam is started from this area. In an area where the second information layer exists, the first information layer is initialized after the second information layer is initialized. Alternatively, the first and second information layers are initialized at the same time by a flash light with adjusted emission time, emission energy, and the like. The first information layer is initialized after the second information layer is initialized by radiating a plurality of flash lights.

    摘要： An optical information recording medium is provided in which the active layer is a phase change material capable of absorbing energy and being converted between a substantially amorphous state and a substantially crystalline state. The active layer contains nitrogen, which may be in the form of a nitride or nitrides of the constituent elements of the active layer, or may be a nitrided surface thereof. The inclusion of nitrogen inhibits localized shifting of the active material, which leads to degradation of the recording/erase properties of the medium. The optical recording medium includes a substrate, onto which is deposited in sequence a first dielectric layer, a nitrogen-containing active layer, a second dielectric layer, and a metallic reflecting layer. The second dielectric layer is made thin, so that the cooling rate of the active layer is increased to form a more uniform amorphous state.
