ABSTRACT:
A molded disc substrate obtained by injection molding is rotated at high speed before the molded disc substrate has solidified, and a gas is also made to flow in an outward radial direction along a bottom surface of the molded disc substrate while the molded disc substrate is rotating, and the rotation is stopped after the molded disc substrate has solidified. Thus, a disc substrate with little warping is obtained in a short time.
