摘要： An optical disk image forming apparatus that forms an image on an optical disk, comprises: an optical disk drive that includes a rotating unit for rotating an optical disk and a laser light irradiating unit being movable in a radial direction of the optical disk; and a control unit that sets a plurality of pixel areas on the optical disk, allocates predetermined writing densities to the plurality of pixel areas, respectively, and controls the optical disk drive to irradiate the laser light onto each pixel area according to the allocated writing densities. When the allocated writing density is a halftone writing density, the control unit corrects the halftone writing density so as to be lighter darker than the allocated writing density.

摘要： An optical pickup is opposed to an inner-radius portion of an optical disc that is set, and pits (a modulation signal) are read by applying laser light for a DVD to the inner-radius portion. The read-out modulation signal is decoded by inputting it to a CD decoder. If decoded disc information includes particular verification data, the optical disc is judged to be a legitimate optical disc of a particular type and formation of a visible image on the label surface is permitted.

摘要： When an image is formed on an optical disk, an optical disk image forming device reads information written in an information area of the optical disk. When a reflection preventing process is applied to an image forming area of the optical disk, the optical disk image forming device corrects at least one of a laser power or a focus gain in accordance with information about the image forming areawritten in the information area. Thus, the optical disk image forming device can form the image with a clear brightness and a good visibility on the image forming area of the optical disk without allowing a rainbow-color to appear or a face or a background to be reflected due to the interference of light.

摘要： An optical disk has inner and outer information areas respectively in inner and outer portions thereof in each of which a groove is formed at a predetermined width. A planar mirror surface is provided without forming a groove, in an area lying between the areas. When a laser beam is applied to the area to form a visible image, visible-image information, capable of representing the position, shape and size of an area occupied by the visible image, is formed and recorded in the area. When additionally forming a visible image, the image area information is read from the area to display on an edit screen an optical disk and an area of a visible image already formed on the surface of the disk. The user is allowed to determine a newly-recording visible image and its position by use of the edit screen.

摘要： A liquid crystal optical device (liquid crystal lens) is located along the optical axis of one of two laser beams emitted by an optical pickup. The two laser beams, which are respectively modulated using a recording pulse and a drawing pulse, are coaxially emitted through the objective lens of the optical pickup, while the focal points are shifted in the light axial direction. A drawing layer and a data recording layer are laminated on an optical disk, and by controlling voltages applied to the liquid crystal optical device, the distance between the focal positions of the two beams is adjusted so that the distance equals the distance between the two layers. While this adjusted state is maintained, one of the laser beams is focused on one of the layers by a focusing actuator, and data recording and drawing are simultaneously performed.
