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 a method of recording/reproducing information associated with an apparatus and recording medium, the medium has an alternate formation including tracks of first regions wherein at least an optical record of preformatted pits at a constant time interval is recorded and second regions in which information is recorded so that optical retrieval can be achieved. A clock signal is generated based on the readout signal of the preformatted pits to record an information signal in the second regions, and the clock signal is retarded and used to read out data pits that are the record of the information in the second regions.

摘要： In a light spot position control system and method in which a control of the irradiation position of a light spot such as a focusing control, a jitter correction and/or a tracking control is made through a sampling control, a newly sampled error value is compared with a one-preceding sampled value. When a difference between both the values is within a range of a predetermined width, the newly sampled value is used as a new sample value as it is. When the difference exceeds the range of the predetermined width, a sum of the one-preceding sampled value and the predetermined width is used as a new sample value. Thereby, the influence of erroneous samples is reduced.
