Abstract

Procedimiento para el registro y reproducción de señales de video sobre una cinta magnéticaen el que la cinta magnética se pasainvirtiéndose periódicamenteante una cabeza magnéticacaracterizado porque como cabeza magnética se emplea una cabeza de pistas múltiples estacionaria respecto a la cinta magnética movidacuyas ranuras al correr hacia delante la cinta magnética se asocian según la técnica de circuitos sucesivamente a las líneas de un semicuadroy el semicuadro se registra o bien se exploramediante exploración por ranurasen forma de cortas pistas superpuestas muy estrechasy al correr hacia atrás la cinta magnética las ranuras de las cabezas se asocian en orden inverso a las filas de su semicuadroestando desplazada la sucesión de pistas en cada inversión en por lo menos una ranuray las ranuras que faltan al final de la sucesión de pistas se completan cíclicamente mediante el correspondiente número de ranuras en el otro final de la serie de ranuras.
