    摘要： An object of the invention is to write-once record and reproduce, or only reproduce, a mark smaller than the resolution limit; obtain a high level of reproduction performance (CNR and the like); and realize a high level of reproduction durability. In the invention, between a signal reproducing functional layer composed of Sb or Te and a protecting layer there is introduced a thermally stable diffusion preventing layer, and thereby reactions between the signal reproducing functional layer and the protecting layer due to increased temperature can be prevented or suppressed while increasing reproduction durability.

    摘要： It is an object of the present invention to provide an optical recording disc which can record data constituted by a recording mark train including recording marks and blank regions neighboring recording marks therein and reproduce the data therefrom in a desired manner even in the case where the lengths of a recording mark and a blank region between neighboring recording marks are shorter than the resolution limit and whose storage capacity can be markedly increased.An optical recording disc is constituted so that data are recorded therein and data are reproduced therefrom with the irradiation with a laser beam and includes a laminated body formed by laminating a decomposition reaction layer 5 containing platinum oxide as a primary component and a light absorbing layer 7 so as to sandwich a second dielectric layer 6. The optical recording disc is further constituted so that when it is irradiated with the laser beam, a bubble pit is formed in the decomposition reaction layer 5 and fine particles of platinum precipitate into the bubble pit, thereby forming a recording mark in the decomposition reaction layer 5 and each of the fine particles of platinum has a particle diameter of 2 nm to 15 nm.

    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 method of at least one embodiment of the present invention of manufacturing a solid-state memory is a method of manufacturing a solid-state memory, the solid-state memory including a recording film whose electric characteristics are varied by phase transformation, the method including: forming the recording film by forming a laminate of two or more layers so that a superlattice structure is provided, each of the layers having a parent phase which shows solid-to-solid phase-transformation, the recording film being formed at a temperature not lower than a temperature highest among crystallization temperatures of the parent phases. It is thus possible to manufacture a solid-state memory which requires lower current for recording and erasing data and has a greater rewriting cycle number.
