In an optical recording disk comprising a substrate, a dye base recording layer, and a reflective layer, the recording layer contains a metal complex having a center metal, and the reflective layer is formed of an alloy of at least two metal elements wherein the total content of a metal element(s) having ionization tendency equal to or greater than the center metal is limited to 0 to 10% by weight. This minimizes reaction between metals in the recording and reflective layers, maintaining the disk reliable. |
