IMPRINT MOLD AND INFORMATION RECORDING MEDIUM SUBSTRATE MANUFACTURING METHOD USING THE SAME

摘要

Provided is an imprint mold having a through hole at a position corresponding to a center hole of a substrate base when the imprint mold is pressed to a molding material.  The through hole is smaller than the center hole. Provided also is an information recording medium substrate manufacturing method using the aforementioned imprint mold.  After the imprint mold is pressed to the molding material, a fluid is introduced into the center hole and the through hole and pressure is applied to the surface of the imprint mold facing the center hole so as to separate the imprint mold from the molding material.  Thus, the imprint mold and the information recording medium substrate manufacturing method using the imprint mold enable easy separation of the mold without scratching the substrate.
