    摘要: An optical recording medium includes a transmissive recording layer containing an oxide of a metal MA, an oxide of a metal MB, and an oxide of a metal MC. The metal MA is at least one kind selected from the group consisting of Mn and Ni. The metal MB is at least one kind selected from the group consisting of W and Mo. The metal Mc is Zr. An atomic ratio (MA/MB) of the metal MA to the metal MB is not less than 0.37 and not more than 1.31. The metal MC is contained in the transmissive recording layer at not less than 0.9 atomic % and not more than 27.5 atomic %.

    摘要: An optical recording medium includes a support substrate and a semi-transmissive recording layer. The semi-transmissive recording layer includes a first dielectric layer, a semi-transmissive semi-reflective layer, a second dielectric layer, a phase change recording material layer, and a third dielectric layer that are sequentially stacked in that order on the support substrate. The semi-transmissive semi-reflective layer contains silver. The second dielectric layer has a stack structure including a lower layer disposed at the interface on the semi-transmissive semi-reflective layer side and an upper layer disposed on the phase change recording material layer side of the lower layer. The lower layer is composed of indium oxide or a composite oxide of indium oxide and tin oxide. The upper layer is composed of tantalum oxide, gallium oxide, zirconium oxide, or niobium oxide.
