A multilayer information recording medium has both good reproducing performance and good recording and rewriting capabilities, as well as good repeated rewriting capabilities even after being archived for a long period of time. The information recording medium has at least a first recording layer and a second recording layer, which generate reversible phase changes between the crystalline phase and the amorphous phase. The first recording layer contains Ge, Te and Bi, while the second recording layer contains Sb and one or more elements M1 selected from a group including V, Mn, Ga, Ge, Se, Ag, In, Sn, Te, Pb, Bi and Au.

An information recording medium includes a first information layer and a second information layer. The first information layer includes a first recording layer in which a reversible phase change is caused between a crystalline phase and an amorphous phase by irradiation of a laser beam or application of current. The second information layer includes a second recording layer in which a reversible phase change is caused between a crystalline phase and an amorphous phase by the irradiation of the laser beam or the application of the current. The first recording layer is made of a first material, the second recording layer is made of a second material, and the first material is different from the second material.
摘要:
A snow vehicle which is capable of increasing the cooling efficiency of an intercooler thereof by reducing the influence of intense heat from a supercharger thereof, while suppressing the overall height of an engine thereof. An engine hood covers a front part of the body frame from above, and an engine room is formed under the engine hood. A supercharger is disposed in the engine room at a location forward of the engine, and an intercooler is disposed rightwardly of the engine. High-temperature air from the supercharger is cooled by the intercooler and supplied to the engine. An air inlet port is formed through a front left half of the engine hood, for taking in air for cooling the supercharger etc., and another air inlet port is formed through a front right half of the engine hood separately from the air inlet port, for taking in air for cooling mainly the intercooler and a battery.

An information recording medium ensures high reliability and favorable overwrite cycle-ability even when an interface layer is not provided between a recording layer and a dielectric layer. The recording layer and the dielectric layers are formed on the surface of the substrate. In the recording layer, a phase change is generated between a crystal phase and an amorphous phase by irradiation of light or application of electric energy. The dielectric layers are oxide-fluoride-based material layers containing one or more oxides which each are an oxide of at least one element selected from a first group including only Ti, Zr, Cr, Hf, Nb, Ta, Cr and Si and one or more fluorides which each are a fluoride of at least one element selected from a second group including only La, Ce, Pr, Nd, Gd, Dy, Ho, Er and Yb.
摘要:
Because conditions for recording identification data of a medium vary in accordance with the structure of different media, such as a single-layer or a multiple-layer structure, stable data recording has been a difficult task. To solve this problem, an incident side of the laser beam for recording identification data on a single-layer optical disk 5 and a double-layer optical disk 6 is the opposite side of a substrate 1 upon which user data is recorded. From this structure, even in a double-layer optical disk 6, the recording is not affected by the recording layer of a second layer 12b and the like. Therefore, in the double-layer optical disk 6, identification data of the medium can be recorded under the same conditions as the single-layer optical disk 5.
