In one embodiment, a thin film solid state lithium ion secondary battery is able to be charged and discharged in the air and manufactured stably at a favorable yield. The thin film solid state lithium ion secondary battery has an electric insulating substrate formed from an organic resin, an inorganic insulating film provided on the substrate face, a cathode-side current collector film, a cathode active material film, a solid electrolyte film, an anode potential formation layer, and an anode-side current collector film. The cathode-side current collector film and/or the anode-side current collector film is formed on the inorganic insulating film face. The anode potential formation layer is a layer formed from the same material as that of the cathode active material film or a material different from that of the cathode active material film and is a layer provided for forming anode potential at the time of discharge.

摘要:
A disk type optical recording medium that can limit the reproduction by a disk drive connected to a computer without drastically changing the specifications of recorded information on the medium conventionally processed by a dedicated player, thereby preventing illegal copying or the like. The disk type optical recording medium has information tracks formed by a pit train, and the information tracks have a read limiting region formed by a modified pit train including a special wobble or lateral displacement as modified from the pit train. In this read limiting region, the modified pit train can be followed by the tracking control of an optical pickup during low-speed rotation of the medium, thereby allowing proper reproduction. However, the modified pit train cannot be followed by the tracking control of the optical pickup during high-speed rotation of the medium, thereby disallowing the reproduction.
摘要:
To accomplish write-once type optical recording mediums that have excellent recording and reproducing characteristics and producibility and that are capable of being fabricated at low cost. A write-once type optical recording medium 10 has the structure of which an inorganic recording film 6, a dielectric film 4, and a light transmission layer 5 have been successively formed on a substrate 1. The inorganic recording film 6 is composed of a metal film 2 and an oxide film 3 successively formed on the substrate 1. When light is radiated to the inorganic recording film 6, oxygen is separated from the oxide film 3 due to the light catalyst effect, resulting in increasing the oxygen concentration on the metal film 2 side and largely varying the optical constant.
