Patent number: 6960269Abstract: A apparatus and method for manufacturing a laminated optical disc that include an adhesive applying device adapted to apply an adhesive to a first substrate, forming an adhesive layer having a specific thickness between the first substrate and a second substrate superimposed onto the first substrate, and a centering device insertable within a common center hole of the superimposed substrates. The centering device includes at least two contact pins configured to simultaneously contact an inside circumferential edge of the common center hole, where the contact pins retractably extend in substantially opposite directions to press against the inside circumferential edge of the common center hole and align the superimposed substrates. The manufacturing apparatus and method may further include a provisional bonding device adapted to partially cure the adhesive layer between the aligned substrates, the provisional bonding device partially bonding and provisionally fastening the aligned substrates.Type: GrantFiled: June 25, 2001Date of Patent: November 1, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hisaki Miyamoto, Kiyoshi Inoue, Hirokazu Itou, Toshikazu Kozono

Patent number: 6309485Abstract: A method and apparatus for the manufacture of laminated compact disc. When forming an adhesive layer between a first substrate and a second substrate, and laminating the first substrate and second substrate to produce a disc, temperature and other conditions are adjusted based on the adhesive layer thickness of the manufactured optical disc, thus the viscosity of adhesive is changed to match each process. Accordingly, high quality discs can be consistently manufactured, and the operating efficiency of the manufacturing apparatus can be improved. Moreover, an optical disc free of bubbles mixed in the adhesive layer of a laminated optical disc can be stably manufactured.Type: GrantFiled: December 17, 1998Date of Patent: October 30, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hisaki Miyamoto, Kiyoshi Inoue, Hirokazu Itou, Toshikazu Kozono
