Abstract

Se da a conocer un aparato de reproduccion de informacion, que comprende un medio de medicion para medir la intensidad de una fluctuacion de una señal leída de un medio de registro de informacion tal como un disco, un medio de almacenamiento para almacenar temporalmente la informacion reproducida a un primer régimen de transferencia, un medio para leer la informacion almacenada en el medio de almacenamiento a un segundo régimen de transferencia que es menor que el primer régimen de transferencia, en donde la velocidad máxima del medio de registro de informacion se gradua para que corresponda a la intensidad de la fluctuacion medida por el medio de medicion.
