Abstract
A magnetic tape reproducing system for providing a still picture of a slow motion picture. A magnetic tape is provided on which video signals are recorded in successive fields of a unit length in the longitudinal direction of the tape and a plurality of rotary magnetic reproducing heads are placed on the periphery of a rotating disc at equal angular intervals from each other so as to reproduce one complete field of the video signals. The magnetic reproducing heads are arranged so that the distance between the two gaps of two adjacent heads is equal to an integral multiple of the distance along the tape corresponding to a period of horizontal synchronizing signals contained in the video signals.
