Abstract:
Disclosed is an optical information recording medium having a printable region on a label surface which is extended to a clamping area, and label information such as a name of a manufacturer is printed in the clamping area. The optical information recording medium includes a substrate having label information pits serving as non-recording and non-reproducing pits that are formed in the clamping area and a reflective layer laminated on the label information pits, and a dummy substrate to be attached to the substrate through an adhesive layer formed on the reflective layer. The multiple label information pits are formed substantially in an entire region of the clamping area to display the label information which emerges by linking portions where the label information pits are not formed.
