摘要： An optical information storage medium includes a multilayer film that includes a plurality of extruded alternating active data storage layers and buffer layers, which separate the active data storage layers. The active data storage layers and buffer layers have thicknesses that allow the active data storage layers to be writable by non-linear or threshold writing processes to define data voxels within the active data storage layers that are readable by an optical reading device.

摘要： An information device is an information device that records information on or reproduces information from an information recording medium (3). The information device includes a light source (14) and a near-field light generating element (9) including a resonating section (22) configured such that plasmon resonance occurs between the resonating section (22) and a recording region (4). The resonating section (22) causes the plasmon resonance when emission light from the light source is irradiated on the near-field light generating element (9). A resonance enhancing film enhances the plasmon resonance between the resonating section (22) and the recording region (4). The resonating section (22) generates near-field light and irradiates the near-field light on the recording region (4) from a recording layer side.

摘要： Provided are a medium structure which allows track narrowing onto a three-dimensional pit selection type disc, and its corresponding optical disc device. Multiple data pit strings are formed between track guide grooves, and a phase-change recording film is formed only in the data pit strings. Thereby, a disc configuration is achieved. Reflectivity and a phase of each of a space portion and a mark portion are appropriately set. Thereby, normal resolution signal cancel is implemented to prevent deterioration in data crosstalk and a push-pull signal. An optical disc medium of the present invention is supported by an optical disc device having a configuration in which a signal is selected from a push-pull signal of a main beam and push-pull signals of sub-beams to read out wobble address information.

摘要： It is an object of the present invention to provide an optical recording disc which can record data constituted by a recording mark train including recording marks and blank regions neighboring recording marks therein and reproduce the data therefrom even in the case where the lengths of a recording mark and a blank region between neighboring recording marks are shorter than the resolution limit, thereby markedly increasing the storage capacity thereof and can improve a C/N ratio of a reproduced signal and the reproduction durability thereof. An optical recording disc includes a substrate 2, a reflective layer 3, a third dielectric layer 4, a light absorption layer 5, a second dielectric layer 6, a decomposition reaction layer 7 containing platinum oxide as a primary component, a first dielectric layer 8 and a light transmission layer 9 and is constituted so that when the optical recording disc is irradiated with a laser beam 20 from the side of the light transmission layer 9, the platinum oxide contained in the decomposition reaction layer 7 as a primary component is decomposed into platinum and oxygen so that a bubble pit is formed in the decomposition reaction layer 7 by thus generated oxygen gas and fine particles of the noble metal penetrate into the bubble pit, thereby forming a recording mark in the decomposition reaction layer 7.
