Abstract
In a magnetic recording system for recording frequency modulated video signals on a magnetic tape field by field at intervals of a predetermined time by a plurality of rotary video heads, during each recording period the rotation speed of the rotary video heads is made different from the steady-state rotation speed and the video signals are recorded thereby making the period of each field of the recorded video signals an integral multiple of the horizontal scanning period.
