摘要： PROBLEM TO BE SOLVED: To provide a cutting method for a original photoresist disk in which a high aperture ratio can be obtained, while variations of the local groove parameters in a land prepit part can be suppressed.
SOLUTION: An exposure region 130 of a continuous spiral shape is formed by irradiating intermittently on a original photoresist disk with a laser beam 101a for forming grooves and irradiating intermittently on the disk with a laser beam 101b for forming land prepits linking with cut-off of the laser beam 101a for forming the grooves. Thereby, as the degree of freedom for a shape of the land prepit and especially, the degree of freedom for the shape of a land overhang part formed at an opposite plane of the land prepit become high comparing with the case in which an one beam cutting method is used, a high aperture ratio can be obtained, while various parameters such as jitter, PI error, or the like can be satisfied synthetically.
