The optical disc recording system comprises a recording medium and a recording device. The recording medium consists of an optical disc having its recording surface made of a material which is writable with a semiconductor laser and has a relatively high rate of laser beam reflection, having a mechanical size like or compatible with the standard size of an optical disc for playback only and having a pregroove of a relatively small depth. The recording device comprises a data signal outputting circuit for outputting an input signal to be recorded at a predetermined transfer speed as a data signal of a mark length recording system compatible with a standard format of the optical disc for playback only, a drive control circuit for driving the recording medium at a standard speed of the optical disc for playback only and controlling positions of the recording medium and the semiconductor laser so as to be compatible with a standard track pitch of the optical disc for playback only, and a laser control circuit for controlling the irradiation state of the semiconductor laser in accordance with the output of the data signal outputting circuit. The recording medium recorded by the recording device is played back by utilizing a playback device for the optical disc for playback only.

    摘要： A teleconferencing apparatus includes the functions of a transmitting unit and a receiving unit and the transmitting unit transmits a sound signal formed from sound pick-up signals of a microphone array made up of microphones Mi (i=1 to N) and position information. The position information is provided by forming a plurality of sound pick-up beams directed in a specific direction and selecting the sound pick-up beam with the largest volume. In the receiving unit, a parameter calculation section sets a virtual sound source based on data of a reception signal and sets a delay parameter. A virtual sound source generation signal processing section forms a sound emission beam based on the parameters and outputs the beam to a loudspeaker SPi.

    摘要： An optical disk recording apparatus is designed for forming pits on a recording surface of an optical disk of a given type at a given recording speed by applying a laser light in the form of a sequence of multiple pulses obtained by intermittently turning on and off the laser light according to a given multi-pulse pattern. In the apparatus, a write strategy circuit is set with a pattern table and controls the turning on and off of the laser light according to a multi-pulse pattern selected from the pattern table in correspondence to a length of the pit to be formed. A storage section stores a plurality of pattern tables of different kinds, each pattern table containing a plurality of multi-pulse patterns corresponding to a plurality of lengths of the pit. A control section selects one of the pattern tables based on either of the recording speed and the type of the optical disk, and reads out the selected pattern table from the storage section and sets the read pattern table in the write strategy circuit.

    摘要： A light-emission responder can respond to input of sound, realizes versatility of response, and can be applied to various use forms. A microphone (110) converts a sound wave into an electric signal. An amplifying section (111) amplifies the electric signal and outputs it to an AGC section (112). The AGC section (112) adjusts the amplitude of the electric signal output from the amplifying section (111). A filter section (113) outputs an electric signal in a frequency band f1 out of the amplitude-adjusted electric signal to a comparing section (114). The comparing section (114) compares the input electric signal with a reference signal. If the voltage of the electric signal passing through the filter section (113) is higher than the reference voltage, the comparing section (114) outputs a signal “H”. When a signal “H” is output from the comparing section (114), a drive section (115) allows a light-emitting element (120) to emit light. A light-emission response output section (116) is connected to the drive section (115). When driven by the drive section (115), the light-emission response output section (116) outputs a radio wave of a predetermined frequency.

    摘要： An optical recording method is designed for recording data on a recordable optical disk by use of a laser beam of a present recording apparatus under a desired recording condition. The method detects identification information which is reserved in the optical disk and which is indicative of a type of a previous recording apparatus. The detected identification information is compared with a plurality of identification information which are previously stored in correspondence to various types of recording apparatuses. As results of the comparison, the method determines whether the detected identification information matches with one of the stored identification information which does not correspond to the type of the present recording apparatus. Upon the determining of matching, the method retrieves a recording condition which is previously stored in association with the matching identification information. The recording of the data is performed on the optical disk by the present recording apparatus with use of the retrieved recording condition.

    摘要： An optical disc has a wobble pregroove which continues in a circumferential direction of the optical disc and wobbles in a radial direction of the optical disc such that the wobble pregroove meanders around a mean center line of meandering. Information recording process is performed by the steps of irradiating an optical beam along the wobble pregroove to form pits, thereby recording information in the form of the pits, and controlling the recording of the information in accordance with a radial distance of the wobble pregroove relative to the mean center line of meandering. Information reproducing process is performed by the steps of irradiating an optical beam along the wobble pregroove to optically detect pits which are formed along the wobble pregroove, thereby reproducing information in the form of the detected pits, and controlling the reproducing of the information in accordance with a radial distance of the wobble pregroove relative to the mean center line of meandering.
