Abstract: PROBLEM TO BE SOLVED: To improve environmental resistance and to increase critical temperature and a critical current density by forming an oxide film that has a specific film thickness and contains an element that can take a plurality of valences at one portion on an oxide superconductor, so that a region with a wide area can be occupied. SOLUTION: An oxide material, made of at least two types of elements that are selected from titanium oxide or Sr, Ti, Ba, Pb, and Zr that are elements for taking a plurality of valences due to chemical stoichiometric composition, is laminated on the surface of an oxide superconductor 4. A film that is laminated on the oxide superconductor surface needs to be at least as thick as 500Å. Also, the area of region where an oxide film is laminated on the superconductor needs to be wider than the area of a region without lamination and is preferably at least two times as wide as the region or wider. For example, after the Y-system superconductor film 4 is worked, the temperature is heated to a specific temperature, and titanium oxide layer 5 is laminated by laser irradiation.

Abstract: PURPOSE:To improve the S/N ratio of reproduction, to speed up recording and erasure, and to prolong the life of a device with simple constitution by using a single-layer crystalline film which has martensite transformation at specific temperature and with specific stress as a recording medium. CONSTITUTION:A preferable recording medium has the reverse transformation of martensite transformation at 150-500 deg.C and has the martensite transformation at -50-120 deg.C. For example, a Cu-Al alloy thin film is used. Then, a light beam is stopped down to about 1mumphi and focused on the recording medium 11 accurately through an objective 15 to heat the medium locally. In this case, a plastic deforming part 3 due to the martensite transformation which is caused locally is used as a recording part and the difference in reflection factor of a light beam between the deforming part 3 and a flat part 4 is detected by a photodetector 17 to reproduce information. When information is erased, the light beam is irradiated so that the temperature of the recording medium 11 is higher than temperature at which the reverse transformation of the martensite transformation occurs, erasing the deformation of the recording part 4. Thus, the performance of the optical information recording device is improved with the simple constitution.

Abstract: PURPOSE:To form a vertical magnetization film with a method having a small thermal load to a base by using a TbCo amorphous ferrimagnetic alloy film for the reproducing layer and the magnetic film with a low Curie temperature than that of the reproducing layer for the recording layer to attain excellent recording and reproducing characteristics. CONSTITUTION:Since a TbCo amorphous ferrimagnetic alloy film having a large Kerr rotary angle and a large reflection luminous amount is used as the reproducing layer, the reproducing characteristic is excellent. The recording layer made of a magnetic film having a lower Curie temperature than the reproducing layer is used in combination with the TbCo amorphous ferrimagnetic alloy film being the reproducing layer with respect to the recording characteristic, the magnetization inversion of the reproducing layer is caused near the Curie temperature of the recording layer. Thus, the excellent recording sensitivity higher than the case of a TbCo film single layer and the same degree as a TbFe single layer only is attained. Further, the film forming method with a small thermal load to the base such as the non-bias sputtering method or the vapor deposition method is used for both the reproducing layer and the recording layer.

Abstract: PURPOSE:To obtain the excellent corrosion resistance of a recording layer consisting of a thin rare earth-transition metal amorphous alloy film having the axis of easy magnetization in the direction perpendicular to the film plane by providing thin anodic oxide films on both surfaces of said recording layer thereby protecting the recording layer. CONSTITUTION:The 1st protective layer 3 on the base body 1 side of the recording layer 4 consisting of the thin rare earth-transition metal amorphous alloy film having the axis of easy magnetization in the direction perpendicular to the film plane out of the protective layers 3, 5 formed respectively on both front and rear surfaces of the layer 4 formed on the substrate 1 is constituted with the thin oxide film provided by the anodic oxidation of the same thin alloy film as the layer 4 in an aq. soln. The 2nd protective layer 5 on the surface of the layer 4 on the side opposite from the body 1 is constituted with the thin oxide film provided by the anodic oxidation of the thin alloy film surface constituting the layer 4 in the aq. soln. A thin light transmittable film 2 is provided between the layer 3 and the body 1. The layer 5 is formed of the thin oxide film of the base itself of the layer 4 and therefore defects such as pinholes are eliminated and the adhesiveness is good. Since the layer 3 is formed of the anodic oxide of the same component as the component of the base for the layer 4, said layer has less defects such as pinholes. The cracking in the stage of forming the layer 3 is prevented by providing the film 2 between the layer 3 and the body 1.
