Abstract

다층 디스크가 각 편면에 기록면이 형성되며 중앙부에 관통공이 형성된 복수개의 디스크 유니트가 적층되어 구성되고 상기 각 디스크 유니트의 중앙부에 형성된 관통공중 적어도 하나가 타 관통공보다 상대적으로 작게 형성된 것에 그 특징이있으며, 이는 다층 디스크의 두께에 관계없이 기존의 클램잉 장치에 장착이 가능한 이점을 가진다.The multi-layer disc has a recording surface formed on each side, and a plurality of disc units having through holes formed in the central portion are stacked, and at least one of the through holes formed in the central portion of each disc unit is formed relatively smaller than the other through holes. This has the advantage that it can be mounted on existing clamping devices, regardless of the thickness of the multilayer disk.
