摘要： A solid-state memory that requires a lower current during recording and erasing data and can repeatedly rewrite data an increased number of times. In at least one example embodiment, the solid-state memory includes a recording layer that includes a laminated structure in which electric properties are changed in response to a phase separation. The laminated structure includes a film containing an Sb atom(s) and a film containing a Ge atom(s), which films constitute a superlattice structure. In the laminated structure, phase separation of the film containing the Sb atom and the film containing the Ge atom allows data to be recorded and erased efficiently.

摘要： When a method for increasing density by providing a tracking guide such as a land/groove and introducing a plurality of strings of super-resolution pits into one track thereof is applied to a reproduction-dedicated optical disk, there are problems in that the production cost is increased, the structure is complicated, and the space which can be used for a recording pits is narrowed because of the land/groove structure.In the invention, a concept of group tracking is applied. One track is formed by a plurality of pit strings having a size not greater than the optical resolution limit in the radial direction and a size not less than or not greater than the optical resolution limit or only not greater than the optical resolution limit in the tangential direction. Reproduction of the super-resolution pit itself is performed by using a non-linear phenomenon generated locally, but, in tracking, a plurality of strings of pits are considered to be one track, and detection of the movement of a laser light for read out is realized by the method used for an existing optical disk by using a reflected light or a transmitted light from the optical disk.

摘要： A simple-structured recording medium without a mask layer and information recording and reproducing methods, which resolve thermal stability related problems arising during reproduction, the recording medium including a high melting point recording layer between first and second dielectric layers. The method of recording information on the recording medium involves irradiating a laser beam onto the recording medium to induce reaction and diffusion in the high melting point recording layer and the first and second dielectric layers. The method of reproducing information recorded on such a super-resolution near-field recording medium by the above method involves generating plasmon using crystalline particles of the high melting point recording layer and the first and second dielectric layers as a scatter source to reproduce information regardless of a diffraction limit of a laser used.

摘要： A method for determining a read power of a laser beam according to the present invention includes a step of setting a power of a laser beam to a recommended recording power Pw′ 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 in an optical recording disc, thereby recording test data therein, a step of setting the power of the laser beam to a recommended read power Pr′ and reproducing the test data recorded in the optical recording disc, a step of judging whether or not signal characteristics of a reproduced signal obtained by reproducing the test data satisfies reference conditions, and determining an optimum read power of the laser beam based on the result of the judgment. According to the thus constituted method for determining a read power of a laser beam, 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 blank regions. Therefore, this method can be applied to an optical recording medium whose storage capacity is markedly increased.

摘要： A phase change optical recording medium has on a substrate a recording layer consisting essentially of a Sb base thin film and a reactive thin film. The Sb base thin film is formed by depositing a Sb base material containing at least 95 at % of Sb to a thickness of 70-150 Å. The reactive thin film is formed of a material which forms a phase change recording material when mixed with Sb. The reactive thin film is typically formed of an In—Ag—Te or Ge—Te material. Stable write/read characteristics are accomplished at the first overwriting, initializing operation is eliminated, and rewriting is impossible at the same linear velocity as recording.
