摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of an optical disk in which formation of minute bubbles in the vicinity of a function layer and a boundary surface are suppressed when a light transmission layer is formed in an information area by spin coat, a read/write error and a servo error caused by minute bubbles can be prevented.
SOLUTION: In this manufacturing method of the optical disk, the light transmission layer is formed by curing coating liquid by spin coat so as to cover an information area of a circular type in which the function layer for information recording is formed from an inner peripheral circle of the prescribed diameter to an outer peripheral side on a disk type substrate. The method comprises a first process in which the disk type substrate is rotated, a second process in which the coating liquid is discharged to a non-information area deviated from the information area of a rotation center side rather than the inner peripheral circle, and a third process in which the disk type substrate is rotated faster than the first process before discharged coating liquid is extended and reaches at least a part of the inner peripheral circle or directly after reaching.
