    摘要: An optical information recording medium is provided which has favorable signal quality even in high density recording using a translucent information layer. The optical information recording medium includes one or more information layers including a recording layer for recording/reproducing an information signal by irradiation with a laser light, and a separating layer or a protective substrate on which a first information layer of the information layer on the irradiation face side is formed, the separating layer or the protective substrate having a guide groove spirally or concentrically formed on the surface, and the respective inclined planes on the inner perimeter side and the outer perimeter side of the guide groove having inclined angles α and β with respect to the bottom face of the guide groove. The guide groove has one or more dissymmetric regions in the radius direction where the inclined angles α and β are different. The information layer has roughly agreeing thicknesses in the inclined face portion on the inner perimeter side and in the inclined face portion on the outer perimeter side in the dissymmetric region.

A first information layer (100) disposed at the front side (viewed from a laser incident side) includes at least a reflection layer (3), a recording layer (6) disposed at the laser incident side with respect to the reflection layer (3), for generating a reversible change between an amorphous phase and a crystalline phase that can be detected optically by applying a laser beam, and a dielectric layer (50) disposed between the reflection layer (3) and the recording layer (6). The dielectric layer (50) contains at least Zr, Si and Cr, a ratio of Zr, Si and Cr of the dielectric layer (50) at the reflection layer side is expressed as Zr:Si:Cr=p:q:r (p+q+r=100), a ratio of Zr, Si and Cr of the dielectric layer (50) in the vicinity of the interface at the recording layer side is expressed as Zr:Si:Cr=s:t:u (s+t+u=100), and r

    摘要: An optical information recording medium of the present invention includes at least m (m is an integer of 2 or more) information layers, and each of the information layers includes a recording layer that changes irreversibly between a state A and a state B that are optically different from each other. In the case where the m information layers are taken as the first through m-th information layers in the order from a laser beam incidence side, when a recording layer included in the j-th information layer (j is an integer satisfying 1≦j≦m−1) is taken as the j-th recording layer, and when a transmittance of the j-th information layer at the time when the j-th recording layer is in the state A is TAj (%) and a transmittance of the j-th information layer at the time when the j-th recording layer is in the state B is TBj (%), the following relationship is satisfied in the j-th information layer: 0≦|TAj−TBj|/(TAj,TBj)max≦0.10 where (TAj,TBj)max is a larger value of TAj and TBj. Furthermore, at least one recording layer of the first through (m−1)th recording layers is formed of a material having a complex index of refraction (n−ik, where n is a refractive index and k is an extinction coefficient) that is different from that of the m-th recording layer.

    摘要: A memory includes: first and second recording layers for recording information by utilizing a reversible phase change between a crystalline phase and an amorphous phase which occurs due to increases in temperature caused by application of an electric current pulse.

Ra1+Ra2, Ra1+Rc2, Rc1+Ra2, and Rc1+Rc2 are different from one another where the resistance value of the first recording layer in the amorphous phase is Ra1, the resistance value of the first recording layer in the crystalline phase is Rc1, the resistance value of the second recording layer in the amorphous phase is Ra2 and the resistance value of the second recording layer in the crystalline phase is Rc2.
