Process and apparatus for producing optical recording medium

A process for producing an optical recording medium comprising an interlayer having a concavo-convex shape, the process comprising:

• (A) forming a first recording layer comprising an organic dye, on which information is to be recorded by applied light, on a substrate directly or via another layer, then
• (B) placing a curable resin material layer, formed by coating by spin coating a precursor of the curable resin, followed by a stamper having a concavo-convex shape for transfer corresponding to the concavo-convex shape on the first recording layer directly or via another layer, then
• (C) partially curing the curable resin material layer in the laminated state, thereby obtaining a bonded body comprising the substrate, the first recording layer, the curable resin material layer and the stamper, then
• (D) separating the stamper from the curable resin material layer so that the concavo-convex shape for transfer is transferred to the curable resin material layer, and applying surface modification treatment to promote curing of the curable resin material layer having transferred the concavo-convex shape for transfer, thereby forming the interlayer, and then
• (E) forming a second recording layer by applying a coating liquid comprising an organic dye on the surface of the interlayer.
