摘要： A method for manufacturing a multilayer information recording medium including at least two information recording layers and a resin layer disposed between the information recording layers that are adjacent to each other includes a first process of filling a resin-containing coating in openings of a screen, electrically charging one of the resin-containing coating filled in the openings of the screen and a predetermined information recording layer using a charging apparatus, followed by applying the resin-containing coating filled in the openings of the screen to the predetermined information recording layer without allowing the screen and the predetermined information recording layer to contact each other, and curing a resin contained in the applied resin-containing coating so as to form the resin layer, and a second process of forming another information recording layer on the resin layer.

摘要： The invention relates to a method for manufacturing a multi-layer information recording medium, including the steps of: forming a thin-film layer on an information surface of a substrate having the information surface; placing a photo-curing resin film and a light transmissive resin stamper on the first thin-film layer followed by pressing; curing the photo-curing resin film by allowing light to pass through the light transmissive resin stamper; forming an information surface by stripping the light transmissive resin stamper from the cured photo-curing resin film; and forming an information layer by covering the information surface with a thin-film layer, wherein the light transmissive resin stamper has a transfer surface used to form the information surface, and a metal thin film is formed on the transfer surface. When a multi-layer information recording medium is manufactured by this manufacturing method, because new information layers can be successively layered from the same surface side, the fabrication sequence can be simplified, which enables in turn to save the manufacturing costs. Also, because the thin-film layer is formed on the surface of the stamper, the stamper alone can be readily stripped from the cured photo-curing resin film with a relative small force. It is thus possible to obtain a multi-layer information recording medium having so high dimensional accuracy without causing stripping in any other layer.
摘要翻译：本发明涉及一种制造多层信息记录介质的方法，包括以下步骤：在具有信息表面的基板的信息表面上形成薄膜层; 将光固化树脂膜和透光树脂压模放置在第一薄膜层上，随后按压; 通过允许光穿过透光树脂压模来固化光固化树脂膜; 通过从固化的光固化树脂膜剥离透光树脂压模来形成信息表面; 并且通过用薄膜层覆盖信息表面形成信息层，其中透光树脂压模具有用于形成信息表面的转印面，并且在转印表面上形成金属薄膜。当通过该制造方法制造多层信息记录介质时，由于可以从相同的表面侧连续层叠新的信息层，所以可以简化制造顺序，从而能够节省制造成本。此外，由于在压模的表面上形成薄膜层，因此能够以相对较小的力从固化的光固化树脂膜中容易地剥离压模。因此，可以获得具有如此高尺寸精度的多层信息记录介质，而不会在任何其它层中产生剥离。
