摘要： A tracking servo system includes in addition to a composite servo system composed of a push-pull track deviation detecting loop operative with pregrooves formed in an optical disc and a wobbling track deviation detecting loop operative with intermittently provided wobbled tracking marks, an offset correcting loop for detecting offset component possibly produced due to tilt, deformation and eccentricity of a recording medium or change in optical and mechanical parameters in the course of time lapse to drive forcibly a light spot by applying an electrical offset to cancel out the offset component. In the offset correcting loop, light reflected by wobbled tracking marks provided intermittently or mirror areas formed by interrupting intermittently the pregroove is utilized for detecting the offset component.

摘要： A non-contact IC card communication in which power consumption of a driver of a reader/writer is reduced and the size of a power supply circuit for operating the driver is made small. The driver has a low output impedance. A current detecting circuit including a detecting coil magnetically coupled with a transceiver coil of the reader/writer through a magnetic coiling element and a resistor detects a current which flows through the transceiver coil. A voltage drop to be detected is small and is approximately constant for a variation of the transceiver coil current. When data is read from an IC card, a load of the driver is changed. The driver drives the transceiver coil in a constant voltage fashion even if a current flowing through the transceiver coil changes due to the change in load. Input voltages of a rectifying/smoothing circuit and a regulator in the IC card become approximately constant. As a result, the amplitude of a high frequency output voltage of the driver can be made small. Also, a high frequency signal current sent from a reader/writer is subjected to double modulation including amplitude modulation by card data and modulation by second information, such as information indicative of the abnormality of an IC card, in synchronism with a timing at which data transmission between the reader/writer and the card is made, and the second information is extracted by the reader/writer.

摘要： In an apparatus for tracking an optical disc, speed in acquiring a steady tracking condition is significant. That is, if the light beam is subjected to feedback while it is positioned in a positive feedback region, e.g., in the middle of adjoining tracks, the track servo system causes an oscillation. Therefore, according to the present invention, there is effected a comparison between the magnitude of signals from two pits disposed offset from the track and a pit on the track to determine the position of the light beam so that the tracking error signal may be inversed when the light beam is positioned in the middle of adjoining tracks. This will operate the tracking system in the negative feedback region to more quickly achieve a stable tracking state.

The pit group forms together with the leading wobbling pit a mark following a predetermined modulation rule applied upon recording of information and changes between tracks adjacent to each other in the radius direction.

摘要： In a radio receiving apparatus, an analog received signal is converted into a digital received signal. An unwanted wave in an adjacent channel band is rejected, that is adjacent to a passband for the digital received signal. The digital received signal with no unwanted wave is converted into a first demodulated signal. The first demodulated signal is converted into a second demodulated signal in analog form. A noise component is extracted from the first demodulated signal. The second demodulated signal is suppressed under squelch control when a squelch voltage that is a voltage of the noise component after rectification and smoothing becomes equal to or higher than a predetermined threshold level.
