An information recording medium includes a transparent substrate, an interference layer formed on the transparent substrate, a recording layer formed on the interference layer, a reflective layer formed on the recording layer, and a coating resin formed on the reflective layer. The recording layer has a pit region and a mirror region. The reflectivity of the pit portion changes as a thickness of the recording layer changes. The reflectivity characteristic of the mirror region is selectively adjustable from that of the pit region within a range of thicknesses of the interference layer.
