設けたビデオテープレコーダ。It has a tracking mono multivibrator triggered by a reproduction control signal, a variable resistor for time constant adjustment, and a time constant capacitor, and the time constant of the multivibrator is variably set without delay time by operating the variable resistor. A video tape recorder includes a tracking time constant circuit in a capstan servo circuit, and servo-controls the running phase of the tape during playback based on the output timing of the multivibrator. A videotape recorder provided with a delay capacitor that adds delay characteristics to the change in the time constant due to variable variation.
