An optical recording medium including a substrate on which a first protective layer, an interface layer , a phase-change recording layer, a second protective layer, an optional third protective layer (anti-sulfuration layer), and a reflective layer are accumulated in this order. The first protective layer contains a mixture of ZnS and SiO 2 . The interface layer contains a material containing Si and O. The phase-change recording layer contains Sn, Sb, Ga, and Ge. In addition, the content of Si and O in the interface layer is 10 to 60 % greater than a content of Si and O in the first protective layer.
