<P>PROBLEM TO BE SOLVED: To provide the manufacturing method of an optical disk by which formation of a bubble at a level difference part and in the vicinity thereof is suppressed when a light transmission layer is formed on an information recording surface by spin coating when the level difference part is present in the vicinity of the information recording surface in the manufacture of the optical disk and a reading/writing error and a servo error caused by the bubble can be prevented. <P>SOLUTION: In the manufacturing method of the optical disk, when the light transmission layer is formed by spin coating so as to cover the information recording surface formed on a disk-like base body, positions at which a UV curing resin d is ejected are changed according to projecting and recessed shapes of the level difference part formed hearer the center part side of the disk-like base body rather than the information recording surface. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
