A method of magnetic recording consisting in line recording of an electric signal on a magnetic medium (1) by means of magnetic heads (8) oscillating in a plane perpendicular to the surface of the magnetic medium with sinusoidally changing speeds the maximum values of which being equal, their periods of oscillation being dividable by the period of the electric control signal and the magnetic heads (8) oscillating in mutual counter-phase mode. A device for implementing the method of magnetic video recording comprises a magnetic medium (1), magnetic heads (8) effecting the line recording of the electric signal and a stable magnetic head (10) effecting the longitudinal recording of the electric control signal. The outputs of delay elements (3), interconnected in series, are electrically connected to mechanisms (14). The device further comprises, interconnected in series, a first frequency multiplier (20), whose input is connected to the electric control signal source (7) and whose output is connected to the input of the mechanism (14) for movement of the magnetic head (8) and to the input of the first delay element (19), a second frequency multiplier (22), a pulse counter (23) and a switch (24) the outputs of which are connected to the windings (22) of the magnetic heads (8). |
