PURPOSE: To obtain a copy tape of high picture quality which does not spoil the quality of an original tape by setting the same tracking condition between a reproducing and a recording side by both servo circuits for recording and reproduction.
CONSTITUTION: An FM luminance signal, low-band converted chromaticity signal, and FM audio signal which are reproduced by a reproducing device are amplified by an amplifier 32 and supplied to the magnetic head 21 in a recording device 36. A tape run mode switching signal and a vertical synchronizing signal which are detected in the device 34 from a playback video signal are supplied to the recording servo 35 in the device 36 from a reproducing servo circuit 33. Consequently, the head 21 rotates synchronously with a magnetic head 4 and synchronous runs are mode between the devices 36 and 34. Therefore, the reproducing signal is recorded in the device 36 in the same tape pattern with a reproducing tape and signal deterioration due to dubbing is reduced by a decrease in the length of a signal path as compared with the conventional device.
