That is, for example, when the ultraviolet curable resin solution 12a applied concentrically on the stamper 30 is pressed into contact with the stamper 30 and the substrate 11 to extend inward and outward of the disc, There has been a problem that bubbles enter the interface with the ultraviolet curable resin solution 12a (after curing, the transfer layer 12). When the substrate 1 is hard like glass, or when the substrate size is large, it is impossible to generate bubbles. Then, there is a problem in that the air bubbles that have entered the transfer layer cannot be recorded / reproduced because it is impossible to form the groove in that portion.
