发明名称 Blank disc and direct stamper and its manufacturing method
摘要 A method for manufacturing a direct stamper to be used for molding optical discs, includes forming a layer of a crosslinkable substance all over a surface of a base disc, subjecting the crosslinkable substance to a first crosslinking reaction, thereafter, forming a photoresist layer on the crosslinking substance, subsequently, subjecting the photoresist layer to exposure to a laser beam having been modulated by a signal to be recorded, and then to development, so that exposed portions of the photoresist are formed into bumps on the crosslinking substance, and thereafter, further subjecting the crosslinking substance and the photoresist bumps to a second crosslinking reaction.
