    摘要: A focus error detection device to be used in an optical system for recording and/or playing back information, including a light detector made up of four light receiving elements arranged symmetrically with respect to the center of the light detector, a multiplication means for generating a pair of multiplication signal by multiplying output signals of two light receiving elements which are arranged symmetrically with respect to the center of the light detector. The multiplication signals are applied to a subtraction means where the focus error signal is generated by the subtraction between the multiplication signals. Thereby the off-set of the focus error signal which has been caused by the deviation of the position of the center of the light beam from the center of the light detector is by far reduced.

    摘要: A video disk player which can read two types of video disk. In the conventional video disk, analog audio channels are recorded in a frequency band between a digital audio channel and a video channel of a narrower bandwidth. In an advanced video disk, there is a digital audio channel and the video channel is extended downward to become adjacent to the digital audio channel. The disk player adjusts the lower frequency cut-off of a video band-pass filter in accordance with a detection of the type of disk, possibly by a special recorded code or by the detection of the analog audio carriers. Preferably, the video band-pass filter comprises a high-pass filter with an adjustable cut-off and a low-pass filter and the frequency-demodulator is positioned between these two filters.

    摘要: A method of measuring the level of crosstalk noise in a playback signal produced from a recording disk such as a video disk, first and second signals of mutually different frequencies are recorded in respective sections of a track in a periodically alternating sequence. These first and second signals are also recorded in corresponding sections of at least one closely adjacent track in a periodically alternating sequence which is displaced with respect to the first-mentioned sequence. Playback of the first track is then repetitively performed, with switching selection of portions of the playback signal from the first sections and second sections respectively, and a derivation of levels of a beat component produced during these selected playback signal portions is obtained. The levels of the beat component are measured, and represent crosstalk noise levels.

    摘要: An on-track and off-track state detecting apparatus in a compatible disk player capable of playing different types of disks, each carrying thereon at least one of a FM audio signal and an EFM signal. The apparatus detects an on-track state and off-track state by comparing the level of the FM audio signal component with a predetermined level, when the disk being played back does not carry the EFM signal, and by comparing the level of the EFM signal component with a predetermined level, when the disk being played back carries the EFM signal thereon. This apparatus commonly uses a level comparator circuit and performs a reliable detection of the respective on-track and off-track states.

    摘要: An optical-disk recording method, recording apparatus and reproducing apparatus are provided which are capable of continuously recording/reproducing a hologram with ultra-high density. In the case of recording a hologram to a holographic recording area, a holographic recording spot HSP on one track of the holographic recording area and a holographic recording spot HSP on a track adjacent thereto are recorded in circumferentially different positions. At least one holographic recording spot HSP is formed on each track, making the process continuous. Recording is made such that, provided that the holographic recording spot HSP has a diameter D and a multiplex number of holographic recording spots HSP is m, a pitch P between adjacent holographic recording spots HSP is P=D/m. Consequently, it is possible to efficiently record a hologram with density to a holographic recording area of an optical disk recording medium, and to achieve the density increase of holographic recording capacity.

    摘要: A method is disclosed, which is capable of subjecting microorganisms to sterilizing or bacteriostatic treatment with good efficiency as compared with the conventional sterilizing or bacteriostatic method using a noble metal electrode. Microorganism-containing water to be treated is electrochemically treated using an anode having conductive diamond to bring the microorganism into contact with the anode, thereby undergoing sterilization. Since the conductive diamond has a high oxidation potential as compared with other electrode substances, direct oxidation reaction due to contact between a microorganism in water to be treated, such as Legionella bacteria, and the anode surface occurs strongly as compared with other electrodes, thereby enabling effective sterilization. The conductive diamond has a high ability to generate ozone and has an excellent formation efficiency with respect to the generation of hydrogen peroxide and radicals. Accordingly, an indirect sterilizing effect can also be expected.
