An optical recording medium is provided having a recording layer that absorbs light with a wavelength of 350 nm to 500 nm, the optical recording medium having good recording playback properties even when the ambient temperature changes, and allowing playback distortion to be controlled even when stored in a high temperature environment. A write-once type optical recording medium including: a substrate; a reflective layer that reflects light with a wavelength of 350 nm to 500 nm on the substrate; a recording layer that absorbs light with a wavelength of 350 nm to 500 nm; and a light transmission layer with a single-layer construction that transmits light with a wavelength of 350 nm to 500 nm, the light transmission layer having a modulus of elasticity at 75° C. that ranges from 50 MPa to less than 170 MPa. |
