を特徴とするディスクの装着機構。A disk that records and reproduces information using light such as a laser. Two transparent thin plates are pasted together in a drum shape through a spacer, and each transparent thin plate has a mounting hole in the center and a pre-grouped recording layer on the inside of each transparent thin plate. When using a device that has tracking information such as a reference circle or a reference circle, or records image information, calculate the relationship between the mounting hole diameter of each transparent thin plate and the hole diameter of the inner spacer. Hole diameter <Spacer inner diameter - (Space inner diameter and transparent thin plate laminating error)
/2, the length of the disk mounting hole guide portion on the mounting mechanism side in the disk thickness direction is 2 of the disk. attachment mechanism.
