Abstract: The optical recording medium has main data recorded on a recording track that has been formed in advance along the track direction, and the recorded data are read out by optical system. Frame synchronising signals based on the same format as the main data format are recorded in advance for each frame that serves as a data recording unit utilising the displacement in the direction of width of the recording track itself, whereby the frame synchronism is easily obtained and the constitution is simplified as a result of using the synchronising circuit in common. The data to be recorded in advance by displacing the track itself in the direction of width include frame synchronising signal as well as any reproduction-only data, in order to increase the recording capacity of the disk. The circuit constitution is simplified by using in common the reproducing circuit for reproducing frame synchronising signals of main data recorded in the track direction of the recording track and the reproducing circuit for reproducing frame synchronising signals of the same format as the main data in the data recorded being displaced in the direction of track width.

Abstract: A three-dimensional object is produced by repeatedly exposing successive layers of liquid photosetting resin at the surface of a quantity of the resin stored in a vessel to a light beam so as to change each light beam exposed layer of the liquid photosetting resin into a solidified layer, stepwise incrementally moving each solidified layer downward into the liquid photosetting resin in the vessel so that a new layer of the liquid photosetting resin is coated on the solidified layer, detecting the temperature of the liquid photosetting resin, and heating the liquid photosetting resin in accordance with the detected temperature to maintain the fluidity of the liquid photosetting resin.

Abstract: A light modulating apparatus for use with a recording apparatus for recording an information signal on a recording medium includes a light source and an acousto-optic modulator for modulating light emitted from the light source in response to a first electrical signal and thereby producing a modulated light signal for acting on the recording medium. Additionally, the apparatus includes an information signal source for providing an information signal, a high frequency oscillator for producing a carrier signal, a signal modulator for modulating the carrier signal by the information signal and providing therefrom the first electrical signal, and a photo-detector for detecting the modulated light signal and producing in response thereto a second electrical signal. The apparatus further comprises a peak-holding circuit for holding substantially a peak value of the second electrical signal, a comparator for comparing the peak value of the second electrical system with a reference signal and providing a corresponding error signal, and an amplitude modulator for controlling the amplitude of the carrier signal in accordance with the error signal.

Abstract: An optical recording medium having an information layer with a reflective film on which an information recording portion is formed by physical change of shape at least in one direction of thickness and track width, said reflective film having such an structure that additional recording can be performed by thermal recording, and that the reflectance of said reflective film changes in the range of 0.5 [%] ~(¦R0-R1¦/R0)x100 [%]~17[%], where R0 is reflectance of non-recording state and R1 is reflectance of recording state for reproducing beam. Such optical recording medium can be manufactured with low cost and additional recording can be done.

Abstract: An optical disk (10) of the present invention has a substrate (11) included a resin-impregnated paper, in which resin is impregnated into paper, or resin-coated paper, in which the paper surface is coated with a resin, and a recording layer (13) formed on at least one side of the substrate (11). This type of optical disk (10) has performance equal to that of conventional optical disks and has a minimal effect on the environment during disposal. In addition, a manufacturing method of an optical disk of the present invention has a recording layer sheet fabrication step in which a recording layer sheet is fabricated by forming tracks on a recording layer base material, and a recording layer sheet lamination step in which a recording layer (13) included the recording layer sheet is provided on a substrate (11) included resin-impregnated paper or resin-coated paper by laminating the recording layer sheet with the resin-impregnated paper in which a resin is impregnated into paper or the resin-coated paper in which the surface of the paper is coated with a resin. This type of manufacturing method of an optical disk allows optical disk (10) to be produced inexpensively.
