ABSTRACT:
A liquid-form adhesive, which is a raw material of the cover layer, is supplied to a plate surface of the disc substrate, which has been set on a turntable, after which a dummy substrate is set on the disc substrate. The dummy substrate is positioned to be concentric with the disc substrate. A setting surface of the dummy substrate is disposed to face the plate surface. In this state, the disc substrate is rotated together with the dummy substrate by rotation of the turntable, and the adhesive is spread to an outer peripheral side of the disc substrate by centrifugal force. Thus, the adhesive fills a space between the plate surface and the setting surface, and is spin-coated on the plate surface. Irregularities in thickness of the applied adhesive are suppressed by the setting surface of the dummy substrate.
