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).

摘要： Video disc reproducing apparatus comprises a pickup (5) having a stylus (5a) in capacative contact with the surface of a video disc (1). The pressure of the stylus (5a) in the disc (1) is adjusted in proportion to a logarithm of the reproduced signal amplitude by a control circuit (15) including a logarithmic converter (11), a rectifier (12) and a low pass filter (13). In a further embodiment the output from an automatic gain control circuit which is used to maintain the output signal constant is used to control the pressure of the stylus.
