An optical information recording medium includes a transparent substrate, a thin film layer formed on said transparent substrate and having a recording film, a thin film protecting film formed on said thin film layer, and a substrate protecting film formed on said transparent substrates. A neutral plane of deformation caused by a temperature change of the optical information recording medium is present within the thin film layer. Consequently, it has become possible to provide an optical information recording medium which can prevent deformation (warpage) caused by temperature and humidity changes and be readily manufactured.
