摘要： To achieve stable, high capacity, high speed recording. Of two light beams emitted from a light irradiation means, one or two beams are made pass through an optical path changeable member whereof at least one of the thickness and refractive index changes continuously or in two or more steps immediately after emission from the light irradiation means, so that a difference is introduced into the optical path length of the two beams, and the focusing point of one beam is made to vary to coincide with a position in the recording layer used for playback or recording. Another light beam is used for servo. Converging of light during recording or read of a multilayer recording medium is performed with higher precision than in the prior art, so higher density, higher capacity recording/playback can be performed.

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： The optical disk medium permits an increase in recording density using a complex refractive index variation of an inorganic oxide film in a super-resolution medium using an inorganic oxide film. The reflectance of the disk increases due to the complex refractive index variation of the inorganic oxide film. Specifically, in the case where the inorganic oxide film is an oxide film comprising Co, a reflect addition film is provided. The effective spot diameter used for read-out is reduced, thereby increasing recording density. By using a material for which the complex refractive index varies sharply, the recording density can be approximately doubled.

摘要： On an insulating film (41) in which a plug (43) as a lower electrode is embedded, a laminated layer pattern of an insulating film (51) made of tantalum oxide, a recording layer (52) made of Ge—Sb—Te based chalcogenide to which indium is introduced and an upper electrode film (53) made of tungsten or tungsten alloy is formed, thereby forming a phase change memory. By interposing the insulating film (51) between the recording layer (52) and the plug (43), an effect of reducing programming current of a phase change memory and an effect of preventing peeling of the recording layer (52) can be achieved. Further, by using the Ge—Sb—Te based chalcogenide to which indium is introduced as the recording layer (52), the difference in work function between the insulating film (51) and the recording layer (52) is increased, and the programming voltage of the phase change memory can be reduced.
