PURPOSE:To obtain an optical information recording medium which exhibits no mechanical deformation even under severe conditions such as high temperature and high humidity, and in which the reflective film itself is also good. CONSTITUTION:In an optical information recording medium such as an optical disk wherein a multilayer film including a recording film 3, reflective film 4 and the like is provided on a substrate 1, a first organic resin layer 5 provided on the multilayer film and a second organic resin layer 6 provided on the substrate 1 opposite to the multilayer film have the same component and film thickness, and the reflective film is made of a highly corrosion-resistant metal mainly containing Au, Pt. |
