Technical Documentation: Troubleshooting Optical Disc Stampers
A clear explanation of the protrusion reduction test that solved issues such as poor molding and reduced shot count.
"Troubleshooting for Optical Disc Stampers" introduces a series of tests aimed at reducing "protrusions" in optical disc stampers while maintaining productivity. When polishing the back surface of optical discs, "protrusions" are cited as a cause of molding defects, signal surface bulging, and reduced shot counts. Through various processes such as finishing electroforming, reviewing filters, and selecting pit prevention agents, a long-term test over six months under final conditions resulted in a significant reduction in the occurrence of "protrusions," making it possible to address them with coarse polishing.
