摘要： A hub-mounted optical disk to eliminate the need for a separate stack ring while decreasing the overall height, a method of fabricating the optical disk, and an injection molding die for manufacturing an optical disk substrate. The hub-mounted optical disk includes a substrate having a hollow and an indented portion engraved to a predetermined depth on the inside of a non-recording surface where no information is recorded; and a hub including a plate that has a fitting hole therein and is engaged into the hollow and the indented portion and a central ring that is inserted into the fitting hole. The method of fabricating the hub-mounted optical disk includes mounting the hub onto a magnetic chuck, applying an ultra-violet (UV) hardening resin on the indented portion of the substrate, operating the magnetic chuck so that the plate is in contact with the indented portion, and curing the UV hardening resin by irradiating it with UV light. The injection molding die for manufacturing the optical disk substrate includes a stationary plate having an injection nozzle that allows resin forming the substrate to be injected, a stamper that has a predetermined information recording pattern, and a moving plate having a projecting portion at the center.

摘要： A swing-arm type optical recording and reproducing apparatus and an optical disk applicable to the same. The optical disk includes a substrate having an information recording surface to record and reproduce an information signal, and a protective layer which is provided on the information recording surface and whose surface facing a slider is a flat even surface so that variations in a floating height of the slider can be reduced. The optical recording and reproducing apparatus further includes, an optical head having a light source provided at a swing arm to emit light of a predetermined wavelength; an optical path changing means provided in the optical path of the light emitted from the light source for changing the proceeding path of incident light; a collimating lens installed at the slider to preliminarily converge the light emitted from the light source and entering via the optical path changing means; an objective lens installed at the slider to converge the light which is emitted from the light source and enters via the optical path changing means to form an optical spot on the optical disk; and a photodetector to receive the light which is reflected from the optical disk and enters via the objective lens, the collimating lens, and the optical path changing means. The optical head detects an information signal and an error signal in order to reduce defocus due to variations in ambient temperature and variations in the wavelength of the light of the light source.

摘要： A disc is produced using a method of and an apparatus for forming a transparent layer on a disc substrate. The method for forming the transparent layer on the disc substrate includes covering an axial hole formed at a center of the disc substrate with a cover element by inserting a protrusion of the cover element in the axial hole of the disc substrate so that a resin does not leak through the axial hole, dispensing the resin toward the center of the disc substrate from an upper side of the disc substrate, and removing the cover element. A more uniform transparent layer can be obtained throughout the disc substrate.

摘要： A reproduction-only optical disc has a lead-in area, a user data area, and a lead-out area. Disc related information recorded on at least one of the lead-in area and the lead-out area is recorded by high frequency groove wobbles, and data of the user data area is recorded by pits. Since the high-density reproduction-only optical disc uses the same channels for reproduction signals as a high-density recordable optical disc, the two types of discs are consistent with each other and are compatible with the same disc drives.

摘要： A method of manufacturing an optical disc includes easily removing a bump formed on a circumference of the optical disc during forming a transparent layer by using a spin-coating method to form the optical disk having a high-density recording capacity. The method includes preparing a substrate having a diameter larger than that of a desired disc, applying an ultraviolet hardening resin to the substrate and forming a transparent layer having a predetermined thickness by a spin-coating method, illuminating an ultraviolet ray on the transparent layer and a bump formed on a circumference of the transparent layer to be hardened, and cutting out the bump by using a puncher. According to the method, the bump which inevitably occurs when the transparent layer is formed, can be easily cut out by a puncher.
