摘要:
An optical recording medium including a light transmitting resin layer which is hardly susceptible to flaws and stripping and is formed with high accuracy, and a manufacturing method and a manufacturing device of the optical recording medium are provided. An optical recording medium 10 includes: a disc-like shaped support substrate 12 having an information recording face 12A on one side; and a light transmitting resin layer 14 formed on the information recording face 12A of the support substrate 12. An annular convex portion 16 projecting in a thickness direction so as to surround a center axis line 12B of the support substrate 12 is formed on the resin layer 14, and the resin layer 14 is extended to the inside of the annular convex portion 16 in a radial direction.
