Abstract

SE PRESENTA UN APARATO DE GRABACION/REPRODUCCION MAGNETICA QUE INCLUYE UN CUERPO DE MECANISMOS, UN CIRCUITO DE CONTROL Y UN CIRCUITO DE MEMORIA. EL CUERPO DE MECANISMOS TIENE UN MECANISMO DE CARGA, UN MECANISMO PARA MOVER LA CINTA Y MEDIOS DE DETECCION PARA CONTAR LAS REVOLUCIONES DEL CARRETE PARA EMITIR UNA SEÑAL QUE SE CORRESPONDE CON LA CUENTA DE LAS REVOLUCIONES DEL CARRETE. EL CONTROLADOR DEL CIRCUITO DE CONTROL CONTROLA EL MECANISMO DE CARGA Y EL MECANISMO PARA MOVER LA CINTA, CALCULA UNA CUENTA ACUMULATIVA DE LAS REVOLUCIONES DEL CARRETE A PARTIR DE LA SALIDA DEL MEDIO DE DETECCION DE CUENTA DE REVOLUCIONES DEL CARRETE, Y CONTROLA LA GRABACION Y REPRODUCCION DE LOS DATOS, QUE INCLUYEN UNA SEÑAL DE VIDEO Y UN NUMERO DE PISTA, EN Y DESDE LA CINTA MAGNETICA. EL CIRCUITO DE MEMORIA ALMACENA LA CUENTA ACUMULATIVA DE REVOLUCIONES DEL CARRETE Y EL NUMERO DE PISTAS EN EL MOMENTO DE LA GRABACION Y REPRODUCCION DE LOS DATOS EN Y DESDE LA CINTA MAGNETICA. EL CIRCUITO DE CONTROL LEE DEL CIRCUITODE MEMORIA UNA CUENTA ACUMULATIVA DE REVOLUCIONES DEL CARRETE QUE SE CORRESPONDE CON UN NUMERO DE PISTA DE UNA POSICION BUSCADA EN LA QUE LA CINTA MAGNETICA DEBE POSICIONARSE, COMPARA LA CUENTA ACUMULATIVA DE REVOLUCIONES LEIDA CON LA CUENTA ACUMULATIVA DE REVOLUCIONES DEL CARRETE DE LA CINTA MAGNETICA QUE SE MUEVE EN UN ESTADO DE NO CONTACTO CON RESPECTO AL TAMBOR GIRATORIO, Y POSICIONA LA CINTA MAGNETICA.
