摘要： Super-resolution technology was proposed for generating marks smaller than the optical resolution in order to record data at high density on the optical disk. However, the achievable high density of the super-resolution technology was limited due to fluctuation of the region exhibiting the super-resolution effect due to the grain size or the molecular size comprising the super-resolution film. However fluctuation in the region exhibiting the super-resolution effect is reduced by utilizing recording marks possessing their own super-resolution effect and also by separating the recording marks from each other.

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： In an information memory apparatus having minute areas for storing information arranged in x, y and z directions three-dimensionally, parallel rays are irradiated to a memory area MA in a direction perpendicular to a z-axis to take projection images of the memory area MA while rotating the memory area MA around the z-axis little by little. The light rays irradiated at this time have a size which covers at least a direction of an x-y plane of the memory area. A computation unit PU finds data and addresses of minute areas distributed three-dimensionally by performing computation based upon the principle of computer tomography on the projection images. As for data writing, a change is given to optical transmissivity or light emission characteristics by irradiating laser light focused by a lens OL placed outside the memory area to a desired minute area and causing heat denaturation within the pertinent minute area.

摘要： Disclosed here is a phase-change recording medium that can solve a conventional problem that high speed overwriting is difficult due to the limitation of the crystallization speed. A linear velocity range (low speed side) usable for recording by overwriting and a linear velocity range (high speed side) usable for write-once recording are written in a predetermined area on the recording medium and the subject system selects either the overwriting or write-once recording according to the linear velocity. The method can thus realize high speed recording easily and less expensively. And, any conventional medium usable only at low linear velocities can be used as is for high speed recording.
