According to the present invention, a cross-sectional shape of a concave-convex pattern formed on a master for an optical information recording medium can be easily controlled using heat-mode recording. The cross-sectional shape of the concavo-convex patter is controlled by using a master substrate which includes a substrate 101, a thermosensitive material layer 102 whose state is changed by exposure, and at least one recording-auxiliary layer 103 which is disposed in contact with the thermosensitive material layer 102, and selecting a thermal conductivity, an optical constant and a thickness of the recording-auxiliary layer 103 so as to thermally and optically control a condition of the thermosensitive material layer during the exposure. |
