METHOD OF MELT-FORMING OPTICAL DISK SUBSTRATES

摘要

The present invention provides a method for the continuous manufacturing of optical memory or optical memory substrates, and/or optical disks, which includes supplying a web of polymeric material between two mating platens, melt-forn-xing at least one microform image, such as an information track structure for an optical device, into the web with a substantially flat stamper, heating a substantial portion of the melt formed cross section of the web of polymeric material to the melt flow temperature (Tf) of the polymeric material. The invention discloses several embodiments for melt-forming an information structure and depositing several layers onto information structure to produce an optical memory device.
