摘要： A multilayer information storage medium according to the present invention includes: a substrate; at least three information storage layers, which are stacked one upon the other on the substrate; a plurality of transparent layers, each of which is arranged between its associated adjacent ones of the information storage layers; and a transparent coating layer. At least two of the transparent layers have mutually different thicknesses. If a laser beam with a wavelength of 400 nm to 410 nm is incident perpendicularly on the medium through the transparent coating layer, two of the information storage layers that sandwich the thinnest one of the transparent layers have a higher returning light intensity and/or a higher degree of modulation than the other information storage layers.

摘要： A method for producing a multilayer information recording medium the method including: holding a substrate; feeding a resin onto the substrate; and removing the excess resin by moving a squeegee throughout the entire surface of the substrate. The substrate may have a resin-coated region, onto which the resin is to be applied, and a non-resin-coated region, onto which the resin is not to be applied. In this case, the resin-coated region has a smaller contact angle with the resin than the non-resin-coated region. The method for producing a multilayer information recording medium may further include, prior to feeding a resin onto the substrate, subjecting a specified area of the substrate to an oil repellent treatment to increase the contact angle of the specified area with the resin.

摘要： Disclosed herein is a method for producing a multilayer information recording medium having at least two information recording layers, in which a resin layer is formed between each pair of the information recording layers, the method including: holding a substrate; feeding a resin onto the substrate; and removing the excess resin by moving a squeegee throughout the entire surface of the substrate so that the interval between the bottom surface of the squeegee and the surface of the substrate is kept constant. The substrate may have a resin-coated region, onto which the resin is to be applied, and a non-resin-coated region, onto which the resin is not to be applied. In this case, the resin-coated region has a smaller contact angle with the resin than the non-resin-coated region. The method for producing a multilayer information recording medium may further include, prior to feeding a resin onto the substrate, subjecting a specified area of the substrate to an oil repellent treatment to increase the contact angle of the specified area with the resin.

摘要： A method is provided for producing a multilayer information recording medium including two or more information recording layers and a space layer provided between adjacent information recording layers. The method includes the steps of: providing a photosensitive adhesive sheet (300) containing an ultraviolet curable oligomer and an adhesive polymer on a predetermined information recording layer (102), attaching a stamper substrate (111) having an uneven surface as an information surface to the photosensitive adhesive sheet so as to transfer information of the stamper substrate to the photosensitive adhesive sheet, curing the photosensitive adhesive sheet after the transfer of the information so as to cause the photosensitive adhesive sheet to be the space layer (103), and peeling off the stamper substrate from the space layer and subsequently forming another information recording layer (104) on the space layer. The photosensitive adhesive sheet has a layered structure including a first resin film (301) and a second resin film (302) as outermost films, and the second resin film contacting the stamper substrate has an ultraviolet curable oligomer content (% by weight) higher than that of the first resin film contacting the predetermined information recording layer.
