Method for manufacturing optical information recording medium

A method for manufacturing an optical information recording medium comprising:

• a first step of forming a substrate material by injection molding, wherein the substrate material has a first guide groove for tracking on a first side of the substrate material, the substrate material being formed as a single layer;
• a second step of forming a second guide groove for tracking by applying an energy-curable resin material between a second side of the substrate material opposite to the first side and a stamper having a pattern corresponding to the second guide groove and subsequently curing the energy-curable resin material by irradiation with energy beam through the substrate material to form a substrate;
• a third step of providing at least one recording layer and a cover layer on a first side of the substrate on which 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, followed by removing the stamper from the substrate to expose the second guide groove;
• and
• a fourth step of providing at least one recording layer and a cover layer on a second side of the substrate on which the second guide groove has been formed.
