摘要: In an optical disc, a first cover layer comprising a filler and a binder is formed on a protective coat, and a second cover layer of at least 0.1 .mu.m thick comprising at least 80% by weight of vinyl pyrrolidone polymer having Mw.gtoreq.30,000 is formed on the first cover layer. The second cover layer is printable with water-based ink. There is obtained an optical disc having a label surface which is printable with water-based ink to form characters and images which are erasable for correction.

摘要: In an optical recording disk comprising a reflective layer in close contact with a recording layer, the recording layer contains a phthalocyanine dye and a second dye having a lower heat decomposition temperature than the phthalocyanine dye. By virtue of a depression of heat decomposition temperature, recording sensitivity is improved.

摘要: The rear surface of a stamper for use in the manufacture of optical disks should be polished to precision. A length of abrasive tape is fed across the stamper in pressure contact with the rear surface of the stamper through a pressure roller having a rubber sleeve with a hardness of up to 80 degrees as measured according to ASTM D 2240 type A while the stamper is rotating.

摘要: An optical recording medium capable of reproduction in accordance with the CD standard is provided. The medium includes a reflective thin film of Ag or similar element, an intermediate thin film of Zn or similar element, and a low-melting thin film of Te or similar element wherein light irradiation causes the reflective thin film element and the low-melting thin film element to diffuse into each other to form an alloy or compound of reduced reflectivity. It is possible to determine through simulation a combination of atoms of the respective thin films which form a cluster having HOMO where electrons in the reflective thin film atoms and electrons in the low-melting thin film atoms do not form a hybrid orbital and LUMO where electrons in the reflective thin film atoms and electrons in the low-melting thin film atoms form a hybrid orbital.
