Molding roll, method for manufacturing it, and apparatus for forming substrate sheet for optical recording medium.

摘要

The present invention provides a molding roll having a relief pattern on its surface. The molding roll comprises a roll base and a stamper fixed on the peripheral surface of the roll base, the stamper being roll-shaped and seamless. Using the molding roll, substrates for optical recording media can be produced successively in which fine patterns corresponding to information are transferred precisely. <IMAGE> <IMAGE>
