摘要： Disclosed herewith is a method for enabling fast and high density recording of information. A voltage is applied to a recording layer formed between a pair of electrodes. The distance between the pair of electrodes is set wider at one of land and groove areas of a subject optical disk and narrower at the other or the distance is set so that light absorption occurs only in either of the land and groove areas. The optical disk is also provided with a layer of which light absorption spectrum changes according to the application of an electric current, thereby absorbing the light. The new layer may be the recording layer itself or a layer adjacent to the recording layer. Because a heat generates only from a small area of the optical disk at the time of recording, the disk can be turned rapidly and permissively to the auto focusing and tracking offsets, thereby enabling fast and high density recording. The disk can thus be formed with easily selectable multiple layers.

摘要： The optical disk medium permits an increase in recording density using a complex refractive index variation of an inorganic oxide film in a super-resolution medium using an inorganic oxide film. The reflectance of the disk increases due to the complex refractive index variation of the inorganic oxide film. Specifically, in the case where the inorganic oxide film is an oxide film comprising Co, a reflect addition film is provided. The effective spot diameter used for read-out is reduced, thereby increasing recording density. By using a material for which the complex refractive index varies sharply, the recording density can be approximately doubled.

摘要： A multilayered optical disk having n recording layers is designed in such a manner that the transmittance Ti of the ith layer from a light-incident side satisfies the relationship: ∏ i - l j - i ⁢ T i 2 ≥ n - j + l n when the light is focused on a recording film of the jth layer. By doing so, the recording/reading property of a multilayered medium is improved.

摘要： Disclosed herewith is a method for enabling fast and high density recording of information. A voltage is applied to a recording layer formed between a pair of electrodes. The distance between the pair of electrodes is set wider at one of land and groove areas of a subject optical disk and narrower at the other, or the disk has multi-recording layer structure and light absorption occurs only in the layer on which coloring voltage is applied. The optical disk is provided with a layer of which light absorption spectrum changes according to the application of voltage, thereby absorbing the light. The layer may be the recording layer itself or a layer adjacent to the recording layer. Because a heat generates only in a selected area of the optical disk at the time of recording, the disk can also avoid cross-talks between layers during reading and can be turned rapidly and permissively to the auto focusing and tracking offsets, thereby enabling fast and high density recording. The disk can thus be formed with easily selectable multiple layers.

摘要： An object of the present invention is to provide a technique for suppressing thermal disturbance of a phase change memory device having a three-dimensional structure. In the phase change memory device having a three-dimensional structure, a material having a high thermal conductivity is used as a gate insulation film of a MOS transistor for selection, and causes heat transmitted to a Si channel layer from a phase change recording film to successfully diffuse to a gate electrode. In this way, since heat generated from a recording bit diffuses to a non-selected bit adjacent to it, it is possible to suppress thermal disturbance. BN, Al2O3, AlN, TiO2, Si3N4, ZnO and the like are useful as a gate insulation film having a high thermal conductivity.

摘要： A super-resolution material is formed in only a data pit, in a low temperature state of the super-resolution material, reflectivity of each of a pit portion and a space portion and an optical phase difference therebetween are set to be sufficiently small, in a high temperature state, and at least the optical phase difference between the pit and the space is set to be larger than the aforementioned value in an absolute value. Accordingly, by conducting irradiation with an appropriate read power by which substantially only one data track width can be heated to a high temperature state, a good push-pull signal can be obtained even with a track pitch being less than a diffraction limit. At the same time, by an optical device having functions such as a switching means with a DPP type, an offset correcting means of the push-pull signal due to lens shift, a shaping means of the push-pull signal, a learning means of read power, and the like, there is provided an optical disk device that corresponds to the optical disk medium of the present invention and achieves an increase in capacity.

摘要： In a super-resolution optical disk for the purpose of achieving an increase in the density of recording data by reproducing a recording mark smaller than optical resolution, the optimum reproduction power needs to be determined since the quality of a super-resolution reproduced signal strongly depends on the reproduction laser power. However, since the track error signal required for tracking servo also depends on the reproduction power, there is a need for a method for determining the reproduction power taking into account both the stabilization of tracking servo and a quality improvement of the reproduction signal. The reproduction power is changed under conditions with focusing servo applied but without application of tracking servo. Thereby, a cross track signal is detected to identify a reproduction power region that leads to quality improvement of both a reproduction signal and a track error signal.
摘要翻译：在超分辨率光盘中，为了通过再现小于光学分辨率的记录标记来实现记录数据的浓度的增加，需要确定最佳再现功率，因为超分辨率再现信号的质量强烈地依赖于对再现激光功率。然而，由于跟踪伺服所需的轨道误差信号也取决于再现功率，因此需要考虑到跟踪伺服的稳定性和再现信号的质量改善两者来确定再现功率的方法。再现功率在聚焦伺服应用的条件下改变，但不应用跟踪伺服。因此，检测交叉轨道信号以识别导致再现信号和轨道误差信号两者的质量改进的再现功率区域。

摘要： When a super resolution technology for optical disks is used in a situation where optical disk management information is formed with a signal that cannot be reproduced by a reproduction method based on a conventional optical disk technology, optical disk drives cannot make recording adjustments and/or reproduction adjustments.An optical disk drive uses an optical disk that forms a management information signal with pits not smaller in size than optical resolution and can be read by a reproduction method based on a conventional optical disk technology. When the optical disk drive records information onto or reproduces information from the optical disk having the super resolution region, it is possible to make proper recording adjustments or reproduction adjustments and perform a proper recording operation or reproducing operation in an optical disk's information region for user information recording or reproduction.
