Provided are an optical recording medium and a method of manufacturing the optical recording medium, in which a reflective film, a dielectric film and a recording film are sequentially formed on a substrate, light being irradiated from an opposite side to the substrate, thereby causing recording and/or reproduction on the recording film to be carried out. At least one of surfaces of the reflective film and the dielectric film is subjected to a smoothing treatment by sputter etching for making a surface roughness equal to 0.75 nm or less. Thus, it is possible to reduce disk noises such as an erasing noise, a recording noise and the like.
