An optical information recording medium has at least an optical reflective layer, an optical recording layer, an protective layer, and an optical transparency layer formed in that order on the main surface of a disc-shaped substrate. An area in which the protective layer is formed is made wider than an area in which the reflective layer is formed, and made narrower than an area in which the optical transparency layer is formed.
