摘要： The top drawing shows a magnetic head structure having means for detecting small capacitive variations which can be processed to give positional information about the head. The head comprises a substrate 32 carrying pole pieces and their associated pick-up coil 38 and contact pads 36,37. The detecting means comprise a coil 26 providing an inductive reactance which is connected between a ground pad 23 and a capacitive pick-up electrode 24. The coil is inductively coupled to input arrangement 27 and to output arrangement 28. The other drawings show the equivalent circuit diagram. In use of the structure an oscillator is coupled to the input arrangement 27 and suitable circuitry connected to output arrangement 28 to detect amplitude modulation of the signal induced therein. These modulations L provide information about the detected capacitive variations.

摘要： A resonance circuit (17) is composed of a capacitor Cs of a ferroelectric layer (2) of a recording medium (1), and a resonator (14). A change of the capacitor Cs of the ferroelectric layer (2) is converted into a frequency of an oscillation signal by the resonance circuit. As the resonator (14), a resonance element having a high Q, such as an SAW resonator, is used.

摘要： It is an object of the present invention to prevent variations in sensitivity of the sensor circuits of the respective channels by equalizing the power of oscillation frequency signals to be distributed/supplied from one oscillation circuit to the sensor circuits of the respective channels. Multi-channel sensor circuits are arranged with a common oscillation circuit. A high-impedance conversion circuit is connected to the output terminal of the oscillation circuit. A first impedance matching circuit for performing impedance matching of resonance circuits of the respective channels with reference to the oscillation circuit is arranged on the output side of the high-impedance conversion circuit. Second impedance matching circuits for performing impedance matching of the oscillation circuit with reference to the resonance circuits are connected at the input terminals of the resonance circuits of the respective channels. The first impedance matching circuit is connected to the second impedance matching circuits through coaxial cables.

摘要： A recording-reproducing apparatus comprises a recording medium provided with a recording layer containing at least two kinds of compounds, which compounds respectively form phases, and having regular periodic structure comprising said phases as constituent units; a probe electrode disposed opposingly to said recording medium; a means for applying a voltage between said recording medium and probe electrode; and a means for detecting an electric current flowing between said recording medium and probe electrode. A recording-reproducing method comprises detecting by the use of a probe electrode, at least one phase on a recording medium of the apparatus and recording information or reproducing the recorded information at the position where said phase has been detected.
