OPTICAL INFORMATION RECORDING MEDIUM AND METHOD FOR MANUFACTURING SAME |
摘要 |
To provide an optical information recording medium capable of attaining high density recording and reducing the leakage of signals to adjacent tracks (cross-talk). The optical information recording medium includes: a first substrate having a pre-groove; an undercoating layer, a dye recording layer, and a reflective layer provided in this order on the first substrate; and a second substrate bonded to the reflective layer via an adhesive layer or a sticky layer, in which the pre-groove has a track pitch of 0.1 to 0.6 µm and a groove depth of 20 to 200 nm.
