摘要：
An optical recording medium includes a first substrate having a groove on the side of an outer peripheral portion thereof; a second substrate in contact with the first substrate in the outer peripheral portion; and a recording layer being disposed in a gap between the first substrate and the second substrate and forming a void in cooperation with the first substrate at the portion of the groove.
