OPTICAL INFORMATION RECORDING MEDIUM.

摘要

PROBLEM TO BE SOLVED: To provide an optical information recording medium capable of suppressing warpage. SOLUTION: The optical information recording medium 100 includes at least one information recording layer 103 on a main surface of a substrate 101 and a light-transmitting layer 106. The substrate 101 includes a clamp area 105 and an information recording area 104 in accordance with the information recording layer 103. In the light-transmitting layer 106, the average thickness of a clamp area correspondent part 106b corresponding to the clamp area 105 is thinner than the average thickness of an information recording area correspondent part 106a corresponding to the information recording area 104.
