Recording drive waveform adjusting method for manufacturing master disc, master disc manufacturing method, master disc manufacturing apparatus, and master disc

摘要

A recording drive waveform adjusting method for manufacturing a master disc is provided. The method includes the steps of forming an exposed area in an inorganic resist layer for test exposure by irradiating a master disc having the inorganic resist layer with laser light of a recording power based on a recording drive waveform according to a test recording signal; obtaining reflected-light information by irradiating the exposed area formed in the test exposure with laser light of a reproducing power; determining whether the recording drive waveform is appropriate by using the reflected-light information; and correcting the recording drive waveform if the recording drive waveform is determined to be inappropriate in the determination.
