Abstract:
Method for manufacturing an optical information recording medium includes: preparing a substrate material where a first guide groove has been formed on a first side of the substrate material; forming a second guide groove by applying an energy-curable resin material between a second side of the substrate material opposite to the first side and a stamper and subsequently curing the energy-curable resin material to form a substrate; providing at least one recording layer and a cover layer on a first side of the substrate where the first guide groove has been formed, while holding the substrate with the stamper left unremoved from the substrate to protect the second guide groove; and exposing the second guide groove by removing the stamper and providing at least one recording layer and a cover layer on a second side of the substrate where the second guide groove has been formed.
