ABSTRACT:
The method and apparatus of making a bonded disk according to this invention is intended to produce bonded disks in a large number at low cost, wherein a bonding strength is not reduced when the inner bonding surface is recessed for title display, it is not deformed easily when stored or left at a high temperature for a long period of time, at least one disk of the paired one-sided disks is formed with a recess for title display where is connected to the stamper clamp groove, a title consisting of desired letters and patterns is printed with an ink on the recess of the one-sided disk, the bonding surface of at least one disk of the paired one-sided disks is applied with a thermoplastic bonding agent while a liquid type reaction setting bonding agent is applied to the recess and the stamper clamp groove of the one-sided disk, and the paired one-sided disks are stacked to bring their bonding surfaces in contact with each other and press them together to form a single bonded disk.
