    摘要: An optical information recording medium on which information can be recorded and reproduced by using a laser beam is provided. The medium includes a substrate with a guide groove and a multilayered metal film including at least a first metal layer, a barrier layer and a second metal layer that are deposited on the substrate in this order, or a single layer metal film including at least a metal layer and a recording layer are deposited on the substrate in this order. The second metal layer and the metal layer of the single layer metal film are a material containing Al and a metal element (an additive) as main components.

    摘要: An optical information recording medium includes the first to the n-th information layers (where n is an integer not less than 3) arranged in this order from a laser beam incident side. Each information layer includes a recording layer containing Te, O and M, where M denotes at least one element selected from the group consisting of Al, Si, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, Zr, Nb, Mo, Ru, Rh, Pd, Ag, In, Sn, Sb, Hf, Ta, W, Re, Os, Ir, Pt, Au and Bi. Concentrations of oxygen atoms contained in the first to the n-th recording layers, namely C(1) to C(n−1), satisfy the following relationships: C(1)≧C(2)≧ . . . ≧C(n−2)≧C(n−1), and C(1)≠C(n−1). When two information layers are included, the oxygen atom concentration of the first information layer is made larger than that of the second information layer.
