Abstract
In the optical information recording medium formed by bonding a dummy substrate (16) onto a substrate (10) for recording and reproduction via an adhesive layer (18), the substrate (10) has a recording area (15) where a pre-groove (101) for tracking is formed and a clamping area (14) where a dummy groove (102) not for recording and reproduction is formed and the groove depth of the dummy groove (102) is made shallower than the groove depth of the pre-groove (101) so that a groove shape after a reflection layer (104) is formed on the dummy groove (102) and a groove shape after a dye layer (103) and the reflection layer (104) are formed on the pre-groove (101) are made nearly equal to each other.
