| 摘要 |
An optical disk manufacturing method including a process of toroidally supplying a first resin on one side of a first disk substrate having an aperture at the center, in a region adjacent to the perimeter of the aperture; a process of rotating the first disk substrate provided with the first resin at a first rotational speed, and spreading the first resin; a process of curing the spread first resin in the surrounding vicinity of the aperture; a process of toroidally supplying a second resin that is superimposed on the first resin of the first disk substrate on which the first resin has cured, in the region adjacent to the perimeter of the aperture; a process of rotating the first disk substrate provided with the second resin at a second rotational speed, and spreading the second resin; and a process of curing the spread second resin.
