ABSTRACT:
An optical recording medium is provided which includes a first substrate having a first information surface, a semitransparent reflection film formed on the first information surface of the first substrate, and a second substrate having a second information surface. In addition, the optical recording medium includes a reflection film formed on the second information surface of the second substrate, and an adhesive layer for adhering the first substrate and the second substrate so that the first information surface of the first substrate faces the second information surface on the second substrate. The thickness of the first substrate is the same as the thickness of the second substrate.
