Abstract
A method for manufacturing an information recording medium may used for manufacturing the information recording medium which has a recording layer and a resin layer that may be provided in contact with the recording layer. In the method, the resin layer is made of at least two kinds of ultraviolet curing resins. First resin layer is formed by screen printing. Second resin layer is formed on the first resin layer as to compensate a surface property. Consequently, a surface nature of the resin layer can be improved.

A method for manufacturing an information recording medium, the information recording medium having an information recording layer which a signal is recorded on and reproduced from by a laser beam directed at the information recording medium and a resin layer on a side of the information recording layer at which the laser beam is directed, the resin layer includes at least two kinds of ultraviolet curing resin, the method comprising:
- forming a first resin layer on the information recording layer by coating with a liquid first ultraviolet curing resin by screen printing;
- and
- forming a second resin layer by coating with a second ultraviolet curing resin having a lower viscosity than the first ultraviolet curing resin by screen printing, so that the second resin layer comes into contact with the first resin layer and the thickness of the first resin layer is greater than the thickness of the second resin layer.
An information recording medium comprising:
- an information recording layer,
- and at least two resin layers formed over the information recording layer, where the resin layers include a first resin layer formed on the information recording layer, and a center line average roughness of the first resin layer surface is greater than a center line average roughness of the resin layer surfaces other than the first resin layer.
