    摘要: A signal transmitter apparatus generates three phase-shifted signals by shifting three transmission signals by predetermined phase shift amounts so that the phase shift amounts of the transmission signals are different from each other by 120 degrees. The signal transmitter apparatus generates three combined transmission signals and outputs the three combined transmission signals to the three transmission conductors, respectively, by combining each of pairs of the phase-shifted signals such that an inverted signal of a first phase-shifted signal is combined with a second phase-shifted signal, when each of the pairs of the phase-shifted signals includes the first and second phase-shifted signals among the three phase-shifted signals and phase shift amounts of the first and second phase-shifted signals are different from each other by 120 degrees. The signal receiver apparatus generates three receiving signals based on received three combined transmission signals, and detects the decoded signals of the transmission signals based on the receiving signals.

    摘要: In a high-frequency impedance type magnetic head having high impedance and capable of efficiently detecting a change in impedance, an electrically conductive metal film is sandwiched between two soft magnetic films, and the two soft magnetic films form a portion of a magnetic path. The thickness of one soft magnetic film is smaller than the thickness of the other soft magnetic film. The electrically conductive metal thin film has a pair of electrodes at respective ends thereof, to which are connected an oscillator for applying a high frequency carrier signal to the electrodes and a high frequency amplifier having a demodulator circuit. Further, an electrically conductive metal film winding is provided, and a DC current is applied to the electrically conductive metal film winding at the time of reproduction, while on the other hand, a signal current is applied to the electrically conductive metal film winding at the time of recording.
