摘要： This invention provides an optical recording medium for recording and reproducing information with light having a wavelength of not more than 700 nm, which has excellent light resistance and can realize good high-speed recording and good high-density recording. The optical recording medium comprises a substrate, a recording layer provided on the substrate and comprising a matrix coloring matter, which, upon exposure to light having a wavelength of not more than 700 nm, can record or reproduce information, and a reflective layer. The recording layer contains an azo-type metal chelate coloring matter additive comprising at least any of Cu2+, Fe2+ and Co2+ as a central metal ion.

摘要： In an optical recording medium 100 having two recording layers of a first recording layer 102 and a second recording layer 105, the second recording layer 105 contains metallized azo dyes represented by the following general formula (I) or (II), and recording characteristics of the second recording layer 105 are improved by having optical density of 1.3 times as large as, or 1.3 times greater than, that of a dye contained in the first recording layer 102. (In this regard, rings A1 and A2 are nitrogen-containing heteroaromatic rings, rings B1 and B2 are aromatic rings, and X is alkyl group substituted by at least two fluorine atoms.)

摘要： An object of the invention is to provide an optical-recording medium in which problems such as cross-write, i.e., signals are recorded wrongly on adjacent tracks, and cross-erase i.e., recording signals on adjacent tracks are erased wrongly, can be solved, and which enables high-density recording; a method for producing the optical-recording medium; and a method for recording and reproducing an optical-recording medium. To achieve this object, the optical-recording medium includes a substrate, an optical-absorption layer which absorbs light and generates heat on or above the substrate, a recording layer, and record-blocking portions which block recording on the recording layer, in which the record-blocking portions are disposed between the recording layer and the optical-absorption layer, and between adjacent tracks, and recording marks are formed on the recording layer by the optical absorption function of the optical-absorption layer.

摘要： Optical information media containing encapsulated data layers are disclosed. Selective layering of materials in inner radial, middle radial, and outer radial zones allows for the faces and edges of at least the data layers to be encapsulated by other materials, resulting in increased resistance to harmful environmental agents such as oxygen and moisture.
