Abstract

Procedimiento de sincronización para registradores magnéticos de gran duración de cinta y de exploración transversal en los que la citna es de gran anchura y de gran longitud y en los que la exploración transversal se efectúa según pistas mangéticas sucesivas caracterizado por el hecho de que un registro magnético de baja frecuencia es superpuesto al registro magnético de frecuencia sonora originando dicho registo de baja frecuencia en la reproducción una corriente eléctrica de misma frecuencia que excita un relé que controla el dispositivo de arrastre del soporte de registro siendo independiente de este relé de control el movimiento de desplazamiento de los órganos magnéticos de reproducción.
