    摘要: An optical information recording medium of the invention has at least two information layers. 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: In each of at least two information layers (1, 2) which constitute a information recording medium having a plurality of information layers on its one side, the compositions of the recording layer (7) and the dielectric layers (6, 8) adjacent to the recording layer (7) in one information layer (1) are common to the compositions of the corresponding layers (12, 11, 13) in the other information layer, so that the recording layers (7, 12) and the dielectric layers (6, 11) and (8, 13) in the two information layers (1, 2) can be formed in common sputtering film-forming chambers without the replacement of targets, which makes it possible to produce a multi-layer single-sided recording medium with a decreased time loss in the production process.

    摘要: An information recording medium of the present invention includes N information layers on a substrate (1), where N is an integer of 2 or more. Information is recorded/reproduced by irradiating each of the information layers (11, 12) with a laser beam (4). When the N information layers are referred to as a first information layer to an N-th information layer sequentially from the opposite side to a laser beam incident side, the L-th information layer included in the N information layers includes at least a recording layer (135) capable of undergoing a phase change through laser beam irradiation, a reflective layer (132), and a transmittance adjusting layer (131) in this order from the laser beam incident side, where L is an integer satisfying 2≦L≦N. The transmittance adjusting layer (131) contains Nb, oxygen (O), and at least one element M selected from Ti, Zr, Hf, Y, Cr, Zn, Ga, Co, Bi, In, Ta, and Ce. In the transmittance adjusting layer (131), the content of Nb is at least 2.9 atom %.
