Abstract
Un aparato de transporte de cinta de carrete a carrete en que una longitud no amortiguada de cinta sigue un camino de longitud sustancialmente fija desde un carrete de suministro pasando por una cabeza de leer/escribir hasta un carrete tomador, y un motor acciona al carrete tomador y otro motor acciona el carrete de suministro para mantener el movimiento de cinta apropiado en la cabeza de leer/escribir, caracterizado por: medios de circuito para proporcionar un solo impulso de paso discriminado cada vez que uno de los carrete gira lo correspondiente a un ángulo preseleccionado relativamente grande; medios de circuito para proporcionar una pluralidad de impulsos, uno cada vez que el otro de los carretes gira lo correspondiente a otro ángulo que es sustancialmente menor que dicho ángulo preseleccionado; medidos de contador para contar los números de dicha pluralidad de impulsos; medios sensibles al impulso único para dar paso discriminado de salida al recuento desde dichos medios de contador;y medios sensibles a cada uno de tales recuentos dejados pasar discriminadamente de salida para proporcionar corrientes a cada uno de dichos motores de una magnitud correspondiente a dicho recuento dejado pasar de salida discriminadamente, de acuerdo con un algoritmo de servo predeterminado, para controlar la rotación de dichos carretes, para proporcionar con ello cambios continuos en las corrientes a medida que cambian los radios de los carretes.
