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 (T
