PURPOSE: To enable a space to be saved and disks to be produced highly efficiently by providing a molder, an ejecting device, a sputter device, a protective film forming device, an inspection device, a printer a control device, and an air cleaner.

CONSTITUTION: A title item enables a molder 2 to produce a disk, an ejecting device to eject the molded disk, a sputter device 4 to form a reflective film, a protective film forming device 5 to form a protective film, an inspection device to inspect the disk, and then a printer 7 to print a label. These process are synchronized to a line and are controlled by a computer control device 8, thus enabling facility management of the above devices and production management such as quality control and material control to be performed simultaneously. Also, an air cleaner 9 which cleans a space where each device is located is installed within a sealed space 1, thus enabling a space to be saved and at the same time disks to be produced efficiently by establishing lines of devices.
