Multilayer Information Recording Medium, and Apparatus and Method for Manufacturing Same

An apparatus for fabricating a multi-layer information recording medium including a substrate, plural information recording layers placed on said substrate, resin intermediate layers placed between adjacent information recording layers and a resin protective layer placed on all the information recording layers at the side opposite from said substrate, said apparatus comprising:

• an ejecting unit including ink jet nozzles operable to drip minute resin liquid drops onto said substrate or said information recording layers;
• and
• a control unit operable to control the ejecting unit, such that the ejecting unit is moved along a relative moving direction, wherein the relative moving direction is parallel to a diameter of the substrate;
• whereby resin layers which form said resin intermediate layers or said resin protective layer are formed on said substrate or said information recording layers.

An apparatus for fabricating a multi-layer information recording medium including a substrate, plural information recording layers placed on said substrate, resin intermediate layers placed between adjacent information recording layers and a resin protective layer placed on all the information recording layers at the side opposite from said substrate, said apparatus comprising:

• a rotating unit operable to rotate said substrate;
• an ejecting unit including ink jet nozzles operable to drip minute resin liquid drops onto said substrate or said information recording layers;
• and
• a control unit operable to control said electing unit,
• wherein said control unit controls said rotating unit to control the rotation speed (with a unit of rpm) of said substrate to equal to or less than five times the viscosity (with a unit of m-Pa) of said resin,
• whereby resin layers which form said resin intermediate layers or said resin protective layer are formed on said substrate or said information recording layers.
