摘要： A method of manufacturing an optical information recording medium that has a substrate having a signal recording layer formed on one principal surface thereof; and an optically transparent layer formed on the signal recording layer and made from a radiation cure type resin. According to the method, when the optically transparent layer is formed, the radiation cure type resin is supplied onto the substrate, and the radiation cure type resin is applied over the substrate by spinning the substrate at a predetermined number of application revolutions in a spin coating method. The number of revolutions of the substrate is increased after the application of the resin, and radiation is irradiated to cure the radiation cure type resin while the number of revolutions of the substrate is increased.

摘要： A method of manufacturing an optical information recording medium to/from which signals can optically be recorded and reproduced. The recording medium includes a signal substrate (100), a signal recording layer (110), and a transparent cover layer (125) having a first transparent layer (115) and a second transparent layer (120), which is harder than the first transparent layer (115). Signals can be recorded and reproduced to and from the recording medium by a light transmitted to the signal recording layer through the transparent cover layer (125). The first transparent layer is formed so as to have a first predetermined distribution of thickness. The second transparent layer is formed so as to have a second predetermined distribution of thickness to make the total thickness of the transparent cover layer (125) uniform. The first transparent layer (115) may be made of a plurality of thin laminated transparent layers.

摘要： A transfer layer on a surface of a mold has a thickness distribution along the radius direction that the layer is thick in an inner round portion but is gradually thinner toward an outer round portion. An adhesive layer is formed between a surface of a signal substrate which bears a signal recording film and the mold which seats the transfer layer. The adhesive layer has a thickness distribution that the layer is thin in an inner round portion but is gradually thicker toward an outer round portion. Since the thickness distributions along the radius direction of the transfer layer and the adhesive layer are opposite to each other, the thickness distribution of an isolation layer which comprises the two layers is uniform.

摘要翻译：模具表面上的转印层具有沿着半径方向的厚度分布，使得该层在内圆形部分中较厚，但是朝向外部圆形部逐渐变薄。在承载有信号记录膜的信号基板的表面和安置转印层的模具之间形成粘合剂层。粘合剂层具有厚度分布，该层在内部圆形部分中较薄，但朝向外部圆形部逐渐变厚。由于沿着转印层和粘合剂层的半径方向的厚度分布彼此相反，所以包括两层的隔离层的厚度分布是均匀的。
