ABSTRACT:
A video signal recording and reproducing apparatus in which video signals based on a plurality of television systems in which the numbers of scanning lines and the frame frequencies are different are recorded by the same VTR. The numbers of effective pixels in one horizontal scanning period and the numbers of effective scanning lines per frame which are based on the respective television systems are made coincident. Only the effective scanning lines are recorded. The rotational speed of the cylinder is also changed in proportion to the frame frequency and tape patterns are made coincident for the respective television systems.
