SOLUTION: A cation polymerizable UV-curing resin 3 as an adhesive is applied with a coating roll 4 on optical disk substrates 1, 2, and the UV-curing resin 3 applied on optical disk substrates 1, 2 is irradiated by an UV-irradiating device 5. Then the two optical disk substrates 1, 2 are temporarily laminated, the optical disk 7 as a laminated body is pressed by a press 6, and the UV- curing resin 3 is hardened. The distance between the rotation axis 41 of the coating roll 4 and the coating face of the optical disk substrates 1, 2 is controlled to const. The relative speed of the rotation axis 41 of the coating roll to the coating face is controlled to const. Further, the thickness of the UV- curing resin 3 deposited on the coating roll 4 is controlled to const by a blade or the like.

    Abstract: PROBLEM TO BE SOLVED: To provide an optical recording medium which is capable of curing of resin at the portions not irradiated with light and has excellent reliability and durability by simplifying production stages in production of a bonding type optical recording medium and a process for producing such optical recording medium at a low cost. SOLUTION: This process for producing optical recording medium is a process for producing optical recording medium formed by providing at least one opposite surface of two substrates facing each other with recording layers and bonding both opposite surfaces to each other with an adhesive, in which a two-pack type adhesive is used as the adhesive and the respective liquids of the two-pack type adhesive is independently applied to at least one of the two substrates. After the two substrates are superposed each other, the two substrates are relatively rotated around their central holes, to spread the mixed two-pack type adhesive between the substrates to cure it.

    Abstract: PROBLEM TO BE SOLVED: To reduce an extension process of adhesive by once by discharging each kind of two liquids constituting the adhesive respectively from two independent piping routes and then uniformly extending them between two sheets of substrates. SOLUTION: One side disk substrate D1 to be stuck to each other is transferred by a substrate transfer device 4 to be vacuum chucked onto a rotary table 21 by vacuum. Then, two liquids type adhesive L1, L2 stored in tanks 31, 34 are discharged respectively from discharge nozzles 33, 36 onto the substrate D1. At this time, both adhesive are discharged annularly and in stratiform in the substrate vertical direction on the substrate D1. Then, another side substrate D2 not applied with the adhesive yet is transferred by the substrate transfer device 4 to be overlapped the substrate D1, and both substrates are rotated together at high speed. The adhesive L1, L2 are expanded uniformly along the substrate is the state keeping a stratiform structure in the substrate vertical direction by an action of centrifugal force at a high speed rotation time. Bubbles mixed in a temporary sticking process are removed out between the substrates together with excess liquid.

    Abstract: PROBLEM TO BE SOLVED: To lessen warpage and deformation and to improve mechanical characteristics, such as wobbling of surface and acceleration of the wobbling of surface, by pressing the ranges of substrates exclusive of their projecting parts via pressing plates provided with substrate contact surfaces having good flatness. SOLUTION: Adhesive layers 3 for sticking two sheets of the substrates 2 having information recording parts on one side are disposed between these substrates 2 and are pressed by the pressing plates 1 from both sides, by which the substrates are stuck to each other. At this time, the ranges exclusive of flashes 2b at the innermost end of the substrates 2, flashes at the outermost peripheral end and the projecting parts in thick parts 2a are pressed by the substrate contact surfaces 1a, which have the high flatness, of the pressing plates 1, by which the substrates are stuck to each other. The pressing plates 1 and the substrates 2 have the high flatness at this time and, therefore, both are fixed at the time of the pressing and are liable to be damaged at the time of peeling. A compressed gas for peeling is blown out to the pressing plates to make the sepn. easier in order to prevent such damage. Further, means 5 for removing dust on the pressing plates 1 is installed in combination in order to prevent the meshing of dust, etc., between the pressing plates 1 and the substrates 2 and the consequent generation of local distortions in the disk and the occurrence of the degradation in its characteristics. As a result, the microdeformation of the disk is prevented.
