装置。[Claim for Utility Model Registration] Obtained by expanding the time axis of the original video signal approximately N times (N = 2, 3, 4, ......) using the horizontal scanning period as a unit, and dividing it into N channels. By shuffling the recorded video signal every field, N inclined tracks are simultaneously formed on the magnetic tape by N rotating magnetic heads, and M sets (M=2) are formed every field. ,3,4,…………)
The magnetic tape is recorded so that the N inclined tracks are formed, and the reproduced video signal obtained by reproducing the magnetic tape by N rotating magnetic heads is deshuffled and the time axis error is corrected. A video signal recording and reproducing device includes: a common memory for the shuffling, deshuffling, and time axis error correction; and a first switching switch that switches between the recorded video signal and the reproduced video signal, and supplies the recorded video signal and the reproduced video signal to the memory for writing. and a second changeover switch that switches the video signal read from the memory and supplies it to a recording circuit and a reproduction circuit.
