ABSTRACT:
A video tape recorder has a pair of rotary magnetic heads spaced apart by 180.degree. from each other on a rotary cylinder which rotates one turn (360.degree.) during each field of a video signal to be recorded. A recording circuit has first and second memories for respectively storing first and second channel component signals of the video signal contained in at least one field for time-compressing them. The first and second memories are controlled to output the time-compressed first and second channel component signals alternately. A reproducing circuit has third and fourth memories for respectively time-expanding the time-compressed first and second channel component signals contained in a reproduced signal to obtain the original two-channel component signals.
