装置。In a playback device that plays back a recorded green signal on a magnetic tape using a rotary head at a tape running speed arbitrarily selected by a playback speed variable operation member within a range of tape running speed from zero to a speed faster than that at the time of recording. the operating member,
The configuration includes a switch that is turned on at a click point when the scale position reaches a position where the tape running speed is approximately the same as during normal playback, and the magnetic tape is turned on based on the signal obtained by turning on the switch. The capstan is equipped with a circuit that generates at least a signal for switching the output signal of the phase control system of the servo circuit of the running capstan to the same output signal as during normal playback, and when the switch is turned on, 1x speed playback is forcibly performed. A magnetic tape playback device configured as follows.
