RECORDING DRIVE WAVEFORM ADJUSTING METHOD FOR MANUFACTURING MASTER DISC, MASTER DISC MANUFACTURING METHOD, MASTER DISC MANUFACTURING APPARATUS, AND MASTER DISC

摘要

PROBLEM TO BE SOLVED: To improve efficiency in adjusting a writing strategy for recording on a master disk.

SOLUTION: An exposed area is formed on an inorganic resist layer by illuminating a laser beam with a recording power to the disk master on which the inorganic resist layer is formed based on the recording drive waveform (a strategy pattern) corresponding to a test recording signal. Reflected light information is obtained by illuminating a laser beam with a reproducing power to the exposed area before development, and whether the recording drive waveform is appropriate or not is determined by using the reflected light information. The recording drive waveform is corrected when the recording drive waveform is not appropriate.
