    摘要: An apparatus for manufacturing an optical disc master, having (a) a turntable upon which is received a disc having a resist layer composed of a resist material, the resist material comprising an incomplete oxide of a transition metal on a substrate, the oxygen content of the incomplete oxide being smaller than the oxygen content of the stoichiometric composition corresponding to a valence of the transition metal, which increases the absorption of ultraviolet rays and visible light rays, the resist material being an amorphous inorganic material containing an oxide; and (b) an exposure system operatively configured to selectively expose the resist layer to ultraviolet rays or visible light.

    摘要: The method of the present invention includes an exposing step in which a laser beam for recording modulated by an information signal corresponding to an information signal of an information concave and convex pattern formed on the optical disc is applied to an inorganic resist layer 101 formed on a substrate 100 to form an exposed pattern corresponding to the information concave and convex pattern on the optical disc, and a development step in which a concave and convex pattern corresponding to the information concave and convex pattern by the inorganic resist layer is formed. By applying a laser beam for estimation to a predetermined area on the inorganic resist layer in the exposing step to estimate recorded signal characteristics of the exposed pattern by the inorganic resist layer using reflected light of the laser beam for estimation, and controlling power of the laser beam for recording based on the estimated result, the aimed information recording on the optical disc can reliably be obtained.

    摘要: A resist material and a nanofabrication method provide high-resolution nanofabrication without an expensive irradiation apparatus using, for example, electron beams or ion beams. That is, the resist material and the nanofabrication method provide finer processing using exposure apparatuses currently in use. A resist layer of an incompletely oxidized transition metal such as W and Mo is selectively exposed and developed to be patterned in a predetermined form. The incompletely oxidized transition metal herein is a compound having an oxygen content slightly deviated to a lower content from the stoichiometric oxygen content corresponding to a possible valence of the transition metal. In other words, the compound has an oxygen content lower than the stoichiometric oxygen content corresponding to a possible valence of the transition metal.

    摘要: A multilayer optical disk having an information storage layer which can as well as be reproduced by a general purpose reproducing apparatus, for example, a compact disk player, and from which information can be read from other information storage layers by using an exclusive reproducing apparatus. The method of manufacturing a multilayer disk comprises the steps of forming a first substrate having a first information storage area enabling reproduction of information therein with a first light beam having a wavelength of 770 nm to 830 nm; forming a second substrate having a second information storage area enabling reproduction of information therein with a second light beam having a wavelength of 615-655 nm but which is relatively transparent with respect to said first light beam; and bonding said first substrate to said second substrate together without said first and second said information areas facing each other.

    摘要: According to the present invention, there is provided an optical recording medium including at least an information recording layer and a reflective film in which the reflective film is comprised of an AgCu alloy thin film containing Cu the content of which is greater than or equal to 3.0 [atomic %] and less than or equal to 6.5 [atomic %]. Thus, the optical recording medium can be made inexpensive and weather resistance of the optical recording medium can be improved, thereby making it possible to avoid characteristics of the optical recording medium from being deteriorated even after it has been stored for a long time.
