摘要： A super resolution optical reproducing system, which can recognize a recording mark less than a resolution limit, removes the effect of a high-frequency noise component of a high power signal obtained by irradiating a laser beam with high read power. The same recording region of an optical recording medium is irradiated according to an irradiation spot by a laser beam with an ordinary read power and an irradiation spot by a laser beam with high read power to obtain a ordinary power signal and a high power signal. The ordinary power signal and the high power signal are normalized to an average level by high pass filters and low pass filters of a high power signal processing circuit and a ordinary power signal processing circuit. Then, a subtracter subtracts the ordinary power signal from the high power signal to obtain a substrated signal. The differential signal and a ordinary reproduced signal that has passed through a parallel processing circuit are amplitude-modulated by a pre-equalizer and a parallel pre-equalizer and then added up by an adder to form a composite signal. The composite signal is output as a reproduced signal.

摘要： A super-resolution optical recording medium has at least a recording layer and a super resolution layer on a substrate. In the recording layer, a minimum recording mark is formed with spaces within a beam spot of a laser beam in recording. The minimum recording mark has a size of a resolution limit of a reproduction optical system or less, and can be reproduced by the reproduction optical system due to the existence of the super solution layer. The minimum recording mark in an AFM image takes the shape of a convex arc on a leading edge thereof and the shape of a concave arc on a trailing edge thereof (the AFM image is a plan view which can be observed on a surface when the light transmission layer is removed), and spaces have the similar shape to these.

摘要： A method for recording information on an optical recording medium in which a laser beam modulated into one or a plurality of write pulses with one or a plurality of write powers in accordance with target data to be written is projected onto a recording layer of the optical recording medium to form a record mark. During recording the information on the optical recording medium, a data level and a weight index are assigned to each channel bit in reference data trains before and after the target data. Recording compensation of the target data is carried out in accordance with the sum totals of the products of the data level and the weight index in the reference data trains, so that it is possible to easily carry out high a real recording by writing fine mark/space trains.

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 method for determining recording laser power on a super-resolution optical recording medium, on which information is recorded on a super-resolution optical recording medium by irradiating a laser beam modulated into a recording pulse train according to recording data to thereby form a recording mark train including recording marks and spaces smaller than the resolution limit of a reproduction optical system and recording marks and spaces equal to or larger than the resolution limit, is provided. At the time of recording, the method determines a minimum value and a maximum value of recordable laser powers determined by test-writing before recording, and determines a maximum value of a recordable range of laser power by adding to the minimum value one-third of a difference between the maximum value of the recordable laser powers and the minimum value. The method determines an optimal range of recording laser power from the minimum value of recordable laser powers to the maximum value of the recordable range.

摘要： An optical recording medium 10 of the present invention has a support substrate 11 and a light-transmitting layer 12, and further has a first dielectric layer 31, a noble metal nitride layer 23, a second dielectric layer 32, a light absorption layer 22, a third dielectric layer 33, and a reflection layer 21, all of which are interposed between the light-transmitting layer 12 and the support substrate 11. In the optical recording medium of the present invention, a laser beam 40 is irradiated on the substrate from the light entrance face 12a, to thus locally decompose the noble metal nitride layer 23, so that record marks can be formed by means of resultant bubble pits. In this case, a gas filling the bubble pits, which are to form the record marks, is a chemically-stable nitrogen gas (N2). The risk of this gas oxidizing or corroding other layers is very remote, and high storage reliability can be achieved.

摘要： An optical recording medium includes a substrate, a first dielectric layer, a recording layer, a second dielectric layer, a super-resolution layer, and a third dielectric layer, which are provided in that order. The super-resolution layer is formed of a material configured such that voids are generated when the material is irradiated with DC light at a predetermined irradiation power for 1 to 300 seconds. Therefore, super-resolution reproduction can be made such that the irradiation power of a readout laser beam does not depend on the size of a recording mark.
