置。 A video recording and reproducing apparatus that includes a field memory for writing a reproduction signal from a magnetic tape during high-speed reproduction, and a memory control circuit that gives a command to read the reproduction signal from the field memory asynchronously with this writing. Means for stopping writing to the field memory to create a read-only state during the transition period between constant-speed playback, and a vertical synchronizing signal for the video signal read from the field memory and a pulse for the rotating head or rotating drum. 1. A video recording and reproducing device comprising means for synchronizing the position with a signal.
