PROBLEM TO BE SOLVED: To provide an optical recording medium that can increase capacity by enlarging a signal area, and a method of producing the optical recording medium.SOLUTION: An optical recording medium includes a substrate, an information layer, and a light transmission layer. A signal area, where the information layer is irradiated with light through the light transmission layer to record and/or reproduce an information signal, extends to a position away by 1.0 mm or more and less than 1.5 mm from the outer peripheral end of the optical recording medium. |
