<p>The present invention provides a method for producing an optical information recording medium whereby soiling or scaring of guide grooves can be suppressed when a recording layer or the like is formed after the guide grooves are formed on both sides of a substrate. A method for producing an optical information recording medium is as follows. A substrate material (10A) on one surface of which first guide grooves (15A) are formed is prepared, an energy-curable resin material is arranged between a surface of the substrate material (10A) where the first guide grooves (15A) are not formed and a stamper (50), and the energy-curable resin material is cured so that second guide grooves (15B) are formed. Then, the substrate (10), to which the stamper (50) is attached, is held in a state in which the stamper (50) is left as a protective member for the second guide grooves (15B), and at least one recording layer (21) and a cover layer are provided on the first guide groove (15A) side. Further, the stamper (50) is separated therefrom so that the second guide grooves (15B) are exposed, and at least one recording layer (21) and a cover layer are provided on the second guide grooves (15B).</p> |
