Abstract
A disc is produced using a method of and an apparatus for forming a transparent layer on a disc substrate. The method for forming the transparent layer on the disc substrate includes covering an axial hole formed at a center of the disc substrate with a cover element by inserting a protrusion of the cover element in the axial hole of the disc substrate so that a resin does not leak through the axial hole, dispensing the resin toward the center of the disc substrate from an upper side of the disc substrate, and removing the cover element. A more uniform transparent layer can be obtained throughout the disc substrate.
