ABSTRACT:
A video signal recording/reproducing apparatus is provided a rotary drum, recording and reproducing heads. Synchronous separation units separate vertical synchronous signals from input and reproduced signals. A memory stores a time difference which represents an elapsed time between when the recording and reproducing heads pass a given location. The time difference stored in the memory is used to control the rotation of the rotary drum.
