Abstract:
1. A method of forming a transparent layer on a disc substrate, supported above a spindle table by a rotation support board and a central axle, having an axial hole formed at a center of the disc substrate, the method comprising: covering the axial hole with a cover element by inserting a protrusion of the cover element in the axial hole of the disc substrate; securing the disc substrate to the spindle table by creating an air flow from either just below the disc substrate through the rotation support board and the spindle table or just below the cover element through the central axle and the spindle table; dispensing a resin toward the center of the disc substrate from a side of the disc substrate; and removing the cover element from the axial hole of the disc substrate.
