Abstract: To produce an optical recording medium having a good concavo-convex shape whereby optical information recording/retrieving is stabilized. A process for producing an optical recording medium 100 provided with an interlayer 104 having a concavo-convex shape, which comprises a step of forming a recording layer 102 on a substrate 101 directly or via another layer; a step of placing a resin material layer 104a and a stamper 110 having a concavo-convex shape for transfer, in this order on the recording layer 102, and curing the resin material layer 104a in this laminated state to obtain a bonded body 112 comprising the substrate 101, the recording layer 102, the resin material layer 104a and the stamper 110, and a step of separating the stamper 110 from the resin material layer 104a so that the concavo-convex shape for transfer is transferred to the resin material layer 104a, and applying surface modification treatment to promote the curing of the resin material layer 104a, to form the interlayer 104.

Abstract: An optical recording medium 300, which is provided with multiple recording layers formed on a transparent substrate to improve a recording characteristic, includes two recording layers (a first recording layer 302 and a second recording layer 305) provided on a transparent first substrate 301 and capable of recording and reading information by use of an irradiated laser beam 310, and an intermediate layer 304 provided between the two recording layers. A predetermined groove serving as a recording track is formed on a surface on an opposite side to the first substrate 301 side in terms of the intermediate layer 304. The intermediate layer 304 is formed of multiple resin layers (a first resin layer 304a, a second resin layer 304b, . . . , and an outermost resin layer 304c).
