In a technique for bonding two disc-shaped resin substrates (D1 and D2) constituting the storage disc (D), the disc-shaped resin substrates (D1 and D2) are centered to correct the nonalignment therebetween. The method comprises steps of placing disc-shaped resin substrates (D1 and D2), which have central holes (DH) and constitutes the storage disc (D) and intervene an adhesive (R) therebetween, on a centering holding table (X1) provided with a boss, spreading the boss (1) inserted into the central holes (DH) the disc-shaped resin substrates (D1 and D2) outward for centering the disc-shaped resin substrates (D1 and D2), and partially irradiating an adhesive (R) interposed between the disc-shaped resin substrates (D1 and D2) with UV rays for curing the disc-shaped resin substrates (D1 and D2) in the vicinity of the centers thereof to temporarily fix the disc-shaped resin substrates (D1 and D2). The nonalignment between the disc-shaped resin substrates (D1 and D2) is corrected, making the quality of the storage disc (D) high. Further, the boss (1) inserted into the central hole of the storage disc (D) is used to center the disc-shaped resin substrates (D1 and D2), which prevents the apparatus from being complex, and manufactures the apparatus at low cost. <IMAGE> |
