  • Publication number: 20070291630
    Abstract: An optical disc production apparatus for producing a disc substrate with one or two signal layers including: a first signal layer forming mechanism for forming a first signal layer on a disc substrate (hereinafter, substrate); a layer forming mechanism which selectively forms a first reflection layer on the first signal layer and forms a second reflection layer on a second signal layer; a second signal layer forming mechanism which forms the second signal layer on the substrate on which the first reflection layer is formed on the first signal layer; a light transmission layer forming mechanism which forms a light transmission layer on the first/second reflection layer; a first transportation mechanism in a loop shape which is arranged close to each of the above-described constitutional element; a second transportation mechanism which is arranged closed to the first transportation mechanism, and which transports the substrate on which the first/second reflection layer is formed on the first signal layer to the

  • Patent number: 6800168
    Abstract: In a plate bonding system for bonding first and second substrate discs (or other plates) with adhesive, there are provided a first section for bringing the first and second substrate discs closer to each other with the interposition of adhesive, and a second section for producing an electric field in the interspace between the first and second substrate discs. The second section produces the field and thereby deforms the adhesive into a tapered shape to minimize the initial contact area and thereby prevent voids from being involved in the adhesive.

  • Patent number: 6228203
    Abstract: A disk bonding system or method comprises a first element for forming an annular adhesive layer on an upwardly facing joint surface of a lower side disk, and a second element for forming a dotted adhesive layer on a downwardly facing joint surface of an upper side disk. Then, a third element sets the upper and lower side disks in a confronting state, and reduces the spacing between the upper and lower side disks until the annular adhesive layer and the dotted adhesive layer are sandwiched between the upper and lower side disks. During this, the annular adhesive layer and the dotted adhesive layer are brought into contact with each other, and the contact region expands in a manner to prevent occurrence of bubbles.

  • Patent number: 5938891
    Abstract: A system for fabricating a bonded disk, comprises an adhesive supplying section for supplying a liquid adhesive on a first disk, a disk handling section for mating the first disk with a second disk, a spin coating section for spreading the adhesive between the first and second disks and a curing section for curing the adhesive. The disk handling section comprises a disk transfer mechanism for arranging the first and second disks in a confronting state in which the first and second disks confront each other and the adhesive supplied to the first disk is interposed between the first and second disks, and for transferring the first and second disks to the spin coating section so that the first and second disks remain in the confronting state.

  • Patent number: 5743965
    Abstract: To improve the reliability, operating speed, size of equipment and economy, a disk coating system for forming a coating on a disk such as a compact disk is arranged to transfer disks to and from a pair of spinners with first and second disk transfer mechanisms. The coating system further has an intermittently rotating turntable, an apparatus for supplying a coating material to each disk on the turntable at a predetermined position, and a system for curing a coating layer on each disk. The spinners for removing an excess amount of the coating material are placed between the turntable and the curing system. The first transfer mechanism is for transferring disks from the turntable to the spinners, and the second transfer mechanism is for transferring disks from the spinners to the curing system. The two spinners are substantially equidistant from a predetermined disk position on the turntable. The first transfer mechanism has two arms extending in two directions diverging from a pivot at a predetermined angle.
