Multilayered information recording medium and process for producing said multilayered information recording medium, and apparatus for producing multilayered information recording medium and screen constituting said production apparatus for producing multilayered information recording medium

An apparatus for manufacturing a multilayer information recording medium comprising at least two information recording portions, a resin layer interposed between the information recording portions, and a signal substrate on which the information recording portions and the resin layer are disposed,

• the apparatus comprising:
• an information-recording-portion forming unit for forming the information recording portions, and
• a resin-layer forming unit for forming the resin layer;
• the resin-layer forming unit comprises a printing section and a resin-curing section;
• where the printing section comprises:
• a screen comprising an application region with a plurality of first pores and a removal region with a plurality of second pores,
• a coating-supplying portion enabling supply of a resin-containing coating on the screen, and
• a squeegee capable of sliding on the screen, and sliding on the screen to allow the resin-containing coating supplied on the screen by the coating-supplying portion to pass the first pores so as to form a coating layer on the information recording portion, and
• a container capable of holding the resin-containing coating that can be removed from the screen surface;
• and
• the resin-curing section has a capability of curing the resin contained in the coating layer,
• wherein the removal region allows at least a part of the resin-containing coating that has not been applied on the information recording portion and that remains on the screen, to pass through the second pores so as to remove the resin-containing coating from the screen surface and into the container.

A method for manufacturing continuously a plurality of multilayer information recording media each having at least two information recording portions, a resin layer interposed between the information recording portions, and a signal substrate on which the information recording portions and the resin layer are disposed, the method comprising:

• a process of forming a predetermined information recording portion on one principal surface of the signal substrate;
• and
• a process of forming the resin layer, the process comprising:
• passing a part of a resin-containing coating, which is supplied on a screen having an application region with a plurality of first pores and a removal region with a plurality of second pores, through the first pores by sliding a squeegee on the screen so as to form a coating layer on the predetermined information recording portion, and curing the resin contained in the coating layer;
• wherein the process of forming information recording portions and the process of forming the resin layer are repeated respectively a predetermined number of times in order to manufacture respective multilayer information recording media;
• and
• at least a part of the resin-containing coating that has not been applied on the respective information recording portions and that remains on the screen is passed through the second pores every time one or a plurality of coating layer(s) is/are formed or during formation of another coating layer, so that the part of the resin-containing coating is removed from the screen surface and into a container for holding the resin-containing.
