Optical information recording medium and a method of manufacturing the same

摘要

An object of the present invention is to provide a method for manufacturing an optical information recording medium and an optical information recording medium itself, forming a stacked layer with a uniform thickness, without being affected by a previously formed underlayer. An optical information recording medium having a light-transmitting layer includes a plurality of resin layers formed on at least one main surface 201a of a substrate 201. To solve the object, in the plurality of resin layers, an inside diameter of the (N+1) (N≥1) resin layer, counted from the substrate is applied, is larger than that of the N resin layer. This method includes a plurality of spin coating methods for covering a center hole 202 of the substrate 201 by a cap, and then forming a resin layer on the substrate 201. The outside diameter of a cap 224 to cover the center hole 202 used for the (N+1) (N≥1) spin coating process is larger than the outside diameter of a cap 214 used for the N spin coating process.
