    摘要: A disk-like, multilayer-structure, information recording medium having a plurality of signal recording layers recording information signals, the medium being formed by pasting together a first substrate, onto which signal recording patterns formed on a first stamper are transferred and which is formed by stamping a sheet on the signal surface of which a semi-transparent film is formed, and a second substrate, which is formed by injection-molding a synthetic resin material, onto which signal recording patterns formed on a second stamper provided in an injection molding machine are transferred, and which is formed with a reflection film on a signal surface thereof onto which signal recording patterns are transferred.

    摘要: The present invention relates to a multi-layered disc-shaped information recording medium having a plurality of signal recording layers each carrying information signals. In preparing the recording medium, a first substrate obtained on punching a sheet obtained in turn by having a signal recording pattern transcribed on it from a first stamper and by forming a semi-transparent film on a signal surface is bonded to a second substrate obtained on injection molding a synthetic resin material. The second substrate is prepared by having transcribed to it a signal recording pattern formed on a second stamper provided on an injection molding device. A reflective film is formed on a signal surface having the transcribed second substrate. The first and second substrates are bonded together on their signal recording layers by a transparent adherent layer.
