摘要： A magneto-optical disk, which possesses a disc-shaped substrate and a recording layer composed of a perpendicular magnetization film that is formed on the substrate, characterized in having: an area wherein magnetic domains having an upward magnetization and magnetic domains having a downward magnetization are alternately aligned along at least one circuit of the disk, the area being formed on the recording layer, the length of the magnetic domains having the upward magnetization being virtually equal to the length of the magnetic domains having the downward magnetization. This invention also has a reproducing method which is characterized in that, when information is reproduced by projecting a light beam onto the magneto-optical recording disk, the intensity of the light beam is adjusted so as to maximize the amplitude of a reproduced signal that is obtained from the area. With the above arrangement, a high-quality reproduced signal can be obtained independent of the characteristics of individual magneto-optical disks.

摘要： A master plate for manufacturing a stamper for injecting molding of an optical memory device has a substrate having a plurality of guiding grooves on a surface thereof with a predetermined interval. The respective edge portions of the guiding grooves are inclined with respect to the surface of the substrate at an angle not more than 30.degree.. According to a manufacturing method of the master plate, the post-baking process is carried out at a baking temperature of not less than 150.degree. C. and an etching gas containing O.sub.2 gas of 4 (SCCM) to 10 (SCCM) is used. Thus, even when the copying is carried out with respect to the substrate of the optical memory device according to the injection molding process wherein the stamper, which is manufactured based on the above-mentioned master plate, is used, the mold release of the stamper can be carried out without being caught by the substrate. Thus, it is possible to keep the respective shapes of the guiding grooves of the s tamper, thereby enabling of manufacturing the substrate of the optical memory device with high repeatability.

摘要： An information reproducing apparatus which has a rotating driver for rotating a disc-shaped recording medium, a floating-type head for reproducing information recorded in the recording medium while floating above the disc-shaped recording medium that is being rotated by the rotating driver, and a suspension, made of an elastic member, for supporting the floating-type head. The information reproducing apparatus is characterized in that the floating-type head has a slider which is floated by an air flow that is directed near the surface of the rotating disc-shaped recording medium, and that the slider has a bevelled portion at one side that faces the outer edge of the disc-shaped recording medium such that any contact between the slider and the ridge that exists along the outer edge area of the disc-shaped recording medium is virtually eliminated. Since the slider is virtually free from contacting the ridge that exists along the outer edge area of the disc-shaped recording medium, the storage capacity of the disc-shaped recording medium can be more effectively used.

摘要： A recording and reproducing device for a magneto-optical card includes an optical head for irradiating a magneto-optical recording medium of a magneto-optical card placed into the device with a laser beam. A magnetic field generator applies a biased magnetic field to the magneto-optical recording medium, and an optical system manipulating mechanism for the optical system of the above-mentioned optical head varies the spot irradiated by the laser beam. The optical head is fixed to the main frame of the device. The magneto-optical card is also supported where it is irradiated by the laser beam emitted from the optical head. The magneto-optical card is moved in a plane parallel to the surface of the magneto-optical card for rough searching and then a part of or the whole magnetic field generator is moved to come into contact with the magneto-optical card to stop the vibration of the magneto-optical card. The spot to be irradiated by the laser beam is then varied by means of the optical system of the optical head.

摘要： An object of the invention is to credibly crystallize an amorphous material for use as a semiconductor material and effect crystallization to a region of desired scope. A first region drawn on a surface of a layer of amorphous material formed on the surface layer of sample (21) is irradiated with laser beam to thereby effect melting, solidification and crystallization of the amorphous material. A second region drawn on the surface of the layer of amorphous material so as to partially overlap the first region is determined, and the second region is irradiated with laser beam to thereby melt the amorphous material within the second region. At the time of solidification of the molten amorphous material, epitaxial growth with the use of the crystal of the first region as a seed crystal is carried out to thereby attain crystallization. Shifting of the first and second regions to be irradiated with laser beam on the surface of the layer of amorphous material and irradiation with laser beam are repeated until the region of crystallization of the amorphous material reaches a desired scope.

摘要： An optical disk has address recording sections each of which has a wobbled part of one of side walls of a groove. Each address recording section is formed by providing convexes of a groove in an adjacent land so as to widen the groove. With the wobbles thus provided in a concavo-convex form, address information is recorded. Besides, the address recording sections thus provided in the grooves are linearly disposed in radial directions of the optical disk. By thus arranging the optical disk on whose grooves and/or lands information is recorded, mixing of wobble frequency components in reproduced information signals does not occur, the sector method is applicable to the optical disk, and information signals of high quality can be obtained.

摘要： An magneto-optical recording medium includes: a transparent dielectric layer; a reproduction layer that is in an in-plane magnetization state at room temperature and changes into a perpendicular magnetization state with a rise in temperature; a non-magnetic intermediate layer; a recording layer made of a perpendicularly magnetized film; and a protection layer, the layers being formed one after another in this order. The recording layer is made of a rare-earth and transition metal alloy, and the rare earth metal is composed of more than two kinds of rare-earth-metal elements containing Gd. The information stored in a magnetic recording domain is masked with respect to a part that is in an in-plane magnetization state. Consequently, recording can be performed with a less powerful laser beam, and each recording bit can be reproduced independently to produce high quality signals even if the converged light beam covers a neighboring recording bit within its radius.

摘要： An optical tape including an optical recording layer for permitting information to be optically recorded thereon and a light-reflective magnetic layer. The light-reflective magnetic layer which reflects light projected onto the recording layer, also permits magnetic recording or magneto-optical recording to be performed thereon, thereby increasing a storage capacity of the optical tape remarkably. Further, the optical tape is provided with a layer to form guiding grooves for tracking control. The layer to form guiding grooves is made up of ultraviolet-hardening resin, photo-resist, or a photochromic material. For example, in the case of using ultraviolet-hardening resin, after a guiding groove pattern has been exposed by projecting an ultraviolet ray on a layer made up of ultraviolet-hardening resin, the exposed areas harden to form areas corresponding to guiding grooves between those exposed areas. The guiding grooves are formed by removing the areas corresponding to guiding grooves from the layer made up of the ultraviolet-hardening resin. Additionally, along with a guiding groove pattern, an index pattern can also be exposed. The guiding grooves thus formed do not reduce the recording density for information of the optical tape.
