    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： A recording mark train is formed in an optical recording medium including a noble metal oxide layer by decomposing a noble metal oxide and deforming the noble metal oxide layer. Noble metal particles are irreversibly deposit in the noble metal oxide layer formed with the recording mark train and a laser beam for reproducing data is irradiated onto the thus deposited noble metal particles, thereby reading the recording mark train. The recording mark train includes at least one recording mark having a length shorter than 0.37λ/NA wherein λ is the wavelength of the laser beam and NA is an optical system for irradiating the laser beam. According to the present invention, in the case of recording and reproducing a recording mark having a size smaller than the resolution limit or a recording mark having a size equal to or larger than the resolution limit but close to the resolution limit in this manner, a high reproduction output can be obtained and a high reproduction durability can be achieved for each of the all recording marks in the recording mark train.
