Abstract
Precision electroforming in replication of optical discs is discussed with overview of electro-forming technology capabilities, limitations, and tolerance criteria. Use of expendable and reusable mandrels is treated along with techniques for resist master preparation and processing. A review of applications and common reasons for success and failure is offered. Problems such as tensile/compressive stress, roughness and flatness are discussed. Advice is given on approaches, classic and novel, for remedying and avoiding specific problems. An abridged process description of optical memory disk mold electroforming is presented from resist master through metallization and electroforming. Emphasis is placed on methods of achieving accuracy and quality assurance.
