ABSTRACT:
This manufacturing device for an optical disc includes: a disc-supporting base on which a disc substrate is mounted; a pin-shaped member arranged at a center of the disc-supporting base, and is movable in the vertical in a center hole of the disc substrate; and a capping member which is slidably placed on a top of the pin-shaped member, and closes the center hole of the disc substrate, wherein when the capping member placed on the top of the pin-shaped member is lowered such that a back face of the capping member contacts an around of the center hole of the disc substrate mounted on the disc-supporting base, the capping member slides on the top of the pin-shaped member.
