Abstract:
A boundary lubricant film 1 is formed on a stamper 22 contact portion of a stationary mirror 21 and/or a stationary mirror 21 contact portion of the stamper 22. The boundary lubricant film 1 contains one of kinds of phosphate esters. A material is injected into a cavity 14. As a result, a disc substrate for an optical disc is molded.
