PROBLEM TO BE SOLVED: To accurately maintain the set thickness of a photosetting resin interposed between plural information recording layers on a substrate independently of the waviness of the substrate and unevenness in the thickness in a multilayered optical recording medium obtd. by laminating the information recording layers. SOLUTION: At least a 1st information recording layer 11 and a 2nd information recording layer 12 are laminated while interposing a transparent resin between the recording layers 11, 12 to obtain the objective recording medium. In this case, spacer particles 30 are dispersed into the transparent resin. |
