    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.

    摘要: An optical recording medium 10 is provided with a supporting substrate 11 and a light-transmitting layer 12, and further has between the light-transmitting layer 12 and the supporting substrate 11 a dielectric layer 31, a noble-metal oxide layer 23, a dielectric layer 32, a light absorption layer 22 and a dielectric layer 33. The second dielectric layer 32 contains as a main component ZnS or a mixture of ZnS and SiO2, and therein the proportion of ZnS to the sum of ZnS and SiO2 is set at a value from 60 mole % to 100 mole %. Since the material of the second dielectric layer 32 has both high hardness and elasticity, and high thermal conductivity besides, excellent balance of thermal conductivity with layer hardness can be achieved and makes it possible to form fine recording marks in true shapes.

    摘要: A method for reproducing data according to the present invention is adapted for reproducing data recorded in an optical recording disc including a multi-layered body formed by forming a decomposition reaction layer containing noble metal oxide as a primary component and a light absorption layer so as to sandwich a dielectric layer therebetween by irradiating a laser beam onto the optical recording disc and forming a recording mark train including at least one of a recording mark having a length shorter than a resolution limit and a blank region having a length shorter than the resolution limit therein, and is constituted by changing the read power Pr of the laser beam in accordance with a readout linear velocity at which data are to be reproduced from the optical recording disc. According to the thus constituted method for reproducing data, even in the case where the length of a recording mark or the length of a blank region between neighboring recording marks is shorter than the resolution limit, it is possible to record and reproduce a recording mark train including these recording marks and the blank regions. Therefore, this method can be applied to an optical recording medium whose storage capacity is markedly increased.

    摘要: The multilayer optical recording medium with at least four or more recording and reading layers disposed one above the other has at least two or more recording and reading layer groups each including the recording and reading layers successively disposed one above the other. In adjacent recording and reading layer groups with an intermediate layer interposed therebetween, a recording and reading layer nearest a front side in the recording and reading layer group nearer a back side is higher than the higher value of the reflectances in a stacked state of two recording and reading layers nearest the back side in the recording and reading layer group nearer the front side.
