Abstract
A method of making an optical disc is disclosed, in which, a flexible imprint mold is made from a fluid-state flexible silicone and has a reversal pattern of a first pattern on a surface. Also, a substrate is provided and has a second pattern on the surface with a semi-reflective layer deposited thereon. A dye or UV curable resin layer is formed on the semi-reflective layer. The flexible imprint mold is used to imprint the dye or UV curable resin layer and allowed to stay on it. After the dye or UV curable resin layer is cured, the flexible imprint mold is released from the cured dye or UV curable resin layer, such that the dye or UV curable resin layer has the first pattern.
