In this device, the gas is decomposed into the ions in the first electrode (1). The decomposed ions are allowed to pass through the ion conductor (3) sandwiched in between the first electrode (1) and the second electrode (2) and conducted to the second electrode (2) side. The conducted ions are reconverted into the gas in the second electrode (2).

    摘要: An optical recording medium on which a data signal is formed comprises an area A of recording tracks for recording a data signal between pairs of grooves Gr and a d.c. offset cancel area B for canceling d.c. offset by the push-pull system, which serves as a predetermined area. In the d.c. offset cancel area B, no grove Gr is formed, and grooves are formed at the recording track center positions Tc. The groove at the recording track center position Tc is caused to have the same width and depth as those of the groove Gr. In carrying out recording/reproduction of a data signal by using this optical recording medium, a return light from the optical recording medium is detected by a bisected detector. A difference signal between outputs from the detector is determined by an amplifier. In accordance with an output signal of a sample-hold signal supply unit, first and second sample-hold units respectively hold signals having output phases different from each other by 180 degrees. An adder adds these signals to take out only a d.c. fluctuation component to eliminate the d.c. fluctuation component superimposed on a tracking error signal at a d.c. offset eliminating unit.

    摘要: An optical pickup is controlled to move to a target track on an optical information storage disc based on target value information representing the sum of speed information indicative of a speed at which the optical pickup is to move, and distance information indicative of a distance which the optical pickup has moved toward the target track. A first subtractor produces a differential signal indicative of the difference between the target value information and remaining distance information which represents a remaining distance that the optical pickup is to move. The differential signal is supplied to a second subtractor which determines the difference between the differential signal and actual speed information indicating an actual speed at which the optical pick is moving. The second subtractor produces a differential signal which is supplied to an actuator to move the optical head.

    摘要: A magnetic modulator coil driving circuit comprises: first and second switching elements for inverting the polarity of exciting currents supplied to magnetic modulator coils, first and second bias voltage setting circuit for determining control voltages to be applied to the first and second switching elements to adjust the currents flowing through the first and second switching elements to a predetermined value, and a data input circuit for supplying modulating data to turn on and off the first and second switching elements alternately. The magnetic modulator coil driving circuit applies a control voltage to the control electrode of the corresponding switching element to control the exciting current to be supplied through the switching element to the corresponding magnetic modulator coil so that the exciting current coincides with a desired value when a reference voltage is applied to the control electrode. Thus a fixed exciting current is supplied to the magnetic modulator coil so that the intensity of the magnetic field may not vary due to temperature variation in the magnetic modulator coil and the magnetic modulator coil may not overheat or burn.

    摘要: A spindle servo system for a magneto-optical recording/playback apparatus, comprising a PLL circuit lockable in phase by sample servo pits formed on a track of a magneto-optical disc; a phase comparator for comparing the phase of a signal, whose period corresponds to the output of the PLL circuit, with the phase of a reference frequency signal; and a resonator having a reference frequency conforming to the eccentricity cycle of the disc. In this servo system, the rotation period of a spindle motor for driving the disc is controlled in accordance with the output of the phase comparator and the output of the resonator. The PLL circuit includes a voltage-controlled crystal oscillator, and the resonator is excited in conformity to the output of the phase comparator to control the rotation frequency of the spindle motor, thereby reducing the jitter component included in the output of the PLL circuit.
