    摘要： By using an information recording medium comprising at least a substrate and an information recording film which is mounted on the above substrate and changes the physical property under irradiation of a recording energy beam, wherein the surface of the information recording area of the above substrate is uneven, both surfaces of the above recording film are also uneven, and an inorganic protective layer is provided in contact with the surface of the above recording film opposite to the above substrate, fine recording points can be formed stably without complicated control of the recording power and recording waveform so that an optical disk unit can record data simply in high density.

    摘要： An initial crystallization method of a recording medium such as a phase-change optical disk, which comprises forming a light spot composed of at least two flat elliptical beam spots each having a long axis direction and a short axis direction and irradiating a rotating recording medium with the light spot such that the long axis direction of the beam spots becomes other direction than the parallel direction to the track direction of the recording medium, wherein the above-described light spot has at least two peaks of light intensity in the short axis direction and the interval of said two peaks of light intensity is 10 &mgr;m or smaller but not smaller than 2 &mgr;m, and a device for carrying out the initial crystallization method. By the initial crystallization method and the device thereof, the initial crystallization of the recording film of the recording medium can be surely carried out at a high speed without causing non-uniformity.

    摘要： An information storage medium includes a substrate, a thin film formed on the substrate and having a reflectance changed by a phase change caused by irradiation of an energy beam irradiated via the substrate and a first reflective layer and a second reflective layer on the film directly or via an intermediate layer. The thin film includes one of In3SbTe2, In35Sb32Te33, In31Sb26Te43 and Ag—In—Sb—Te. The first reflective layer and the second reflective layer are piled up in the recited order from a thin film side with the first reflective layer consisting of a material having an attenuation factor k of 2 or less and selected from a group of silicon based materials and the second reflective layer consisting of a material having an attenuation factor k of at least 3.
