This invention provides an optical information recording medium that has satisfactory main information recording characteristics and in which burst cutting area (BCA) marks can be formed without damaging a protective layer or a light-transmitting layer is provided. In forming the light-reflecting layer by vapor deposition, sputtering, ion-plating, or the like, part of the region is masked so as to make the thickness and/or material of the light-reflecting layer in a main information recording region where main information is recorded different from that of the light-reflecting layer in a BCA equivalent region. As a result, burst cutting of the light-reflecting layer in the BCA equivalent region becomes easier than in the main information recording region thereby achieving the object.
