Abstract
A substrate formed of an organic-inorganic hybrid material and provided with a reinforcement member in an inner periphery portion is used, as a signal transfer substrate, in a method for procuring a multilayer information recording medium having 'n' information recording layers ('n' is an integer of two or more), the method including: applying an ultraviolet curable resin on a “k”th information recording layer (“k” is an integer of from 1 to (n−1)); bonding the signal transfer substrate having a signal surface including a concavo-convex shaped signal portion, to the applied resin, with the signal surface facing the resin; curing the resin by applying an ultraviolet ray to the resin from the substrate side while the substrate is bonded to the resin; and peeling the substrate from the cured resin by warping the inner periphery portion of the substrate. This method enables the signal transfer substrate to be used repeatedly.
