Optical information recording medium and manufacturing method thereof

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 mum and a groove depth of 20 to 200 nm.
