Abstract

Dispositivo de bucle de servo-control perfeccionado previsto en particular para equipos de grabación y/o reproducción de información, cuyo dispositivo está provisto de un tacómetro que está acoplado con un elemento rotativo, cuyo tacómetro tiene una pluralidad de marcas dispuestas en una pista cerrada para, conjuntamente con un detector suministrar n impulsos tacométricos por revolución del elementos rotativo, un circuito de corrección para suministrar n señales de corrección en sincronismo con los impulsos tacométricos, de modo que se compensen las desviaciones de las señales de control que entre otras cosas son causadas por errores posicionales de las marcas, un detector de error de fase para medir la diferencia de fase entre los impulsos tacométricos y una señal de referencia en sincronismo con los impulsos tacométricos y para suministrar señales de error de fase correspondientes, y un dispositivo de control para accionar el elemento rotativo en independencia de dichas señales de error de fase, caracterizado porque el circuito de corrección está provisto de un dispositivo de memoria con n posiciones de memoria, capaz de almacenar n señales de error de fase en dichas n posiciones de memoria en sincronismo con los impulsos tacométricos cuyas señales de error representan errores de fase entre los impulsos tacométricos y la señal de referencia, y un sistema de lectura para leer estas n señales de error de fase en sincronismo con los impulsos tacométricos de modo que se obtengan las n señales de corrección, al paso que el dispositivo de bucle de servo-control comprende además un circuito de suma para sumar las señales de error de fase suministrada por el detector de error de fase y las señales de corrección suministrada por el detector de error de fase y las señales de corrección suministrada por el dispositivo de memoria, unas con otras, con polaridad opuesta, y para suministrar la señal de suma al dispositivo de control en calidad de señal de control
