Abstract

PURPOSE:To attain the assembling of a disk easily and in a short time by mounting a ring to the inner diameter of a disk to be assembled, penetrating two disks to a cylinder and sticking both disks with a special method. CONSTITUTION:By mounting a ring 11 having an outer diameter coincident to the inner diameter of respective disks 1 and 1' to the inner diameter part of respective disks 1 and 1' and penetrating the central hole of the diameter of the same diameter as the central hole for positioning formed at the ring 11 to a cylinder 20, two disks 1 and 1' are stuck while the central position is made coincident. Further, after one of metallic disks 2 is fitted to one side of the disk 1 while the central hole is penetrated to the cylinder 20, the ring 11 is removed from both disks 1 and 1', the central hole of one of the metallic disks 2 and other of the metallic disks 2 is penetrated to the cylinder 20 and other of the metallic disks 2 is fitted to other side of the disk 1. Thus, an optical disk can be assembled easily, in a short time and with a good accuracy.
