Method and apparatus for manufacturing resin stamper, imprint method, magnetic recording medium, and magnetic recording/reproducing apparatus

摘要

The present invention provides a technique capable of manufacturing a resin stamper at a low cost. A method of manufacturing a plate-shaped resin stamper includes: pressing a resin composite base material against a mother stamper having a pattern formed on the surface thereof by compression molding to transfer the pattern of the mother stamper to the composite base material; and punching the composite base material. In the manufacturing method, the resin composite base material includes at least one curing resin. In addition, during the compression molding, a portion of the composite base material is cured by active energy beams or heat, the pattern is transferred to the composite base material, and the composite base material is punched, thereby manufacturing the resin stamper.

1. A method of manufacturing a resin stamper, comprising the steps of:
pressing a resin base material against a mother stamper having a pattern formed on the surface thereof to transfer the pattern of the mother stamper to the surface of the base material by compression molding; and punching the base material so that a punched portion is formed inside the pattern forming portion, and wherein, after the base material is punched so that the punched portion is formed inside a pattern forming portion, a step (1) of using the punched portion to align the mother stamper with the base material, and pressing the base material against the mother stamper by compression molding to transfer the pattern of the mother stamper to the base material, and a step (2) of curing a portion of the base material are performed.
