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： An endless tape reproducer which reproduces an endless tape on which a signal such as video signal is recorded. An object of the reproducer is to reproduce a recording medium at a high degree of accuracy for an extended period of time by employing a recording medium which can be readily duplicated and which is capable of recording a large quantity of signals. The endless tape (2) is wound on a stationary reel (1), and the portion of the tape at the innermost periphery thereof is introduced into the interior of the reel (1) and wound on the outermost periphery of the tape (2) over the reel (1) through a capstan (4) and a pinch roller (5). The endless tape (2) has a conductive layer, on which a signal is recorded as an irregular pattern. An electrostatic head (7) has an electrode facing the tape (2), and reproduces a signal recorded on the tape (2) due to the variances in the electrostatic capacity between the electrode and the irregular pattern on the tape (2).
