Abstract
Sistema de protección anti-copia para CD ROM y/o DVD ROM. El sistema está concebido para evitar la reproducción de los archivos contenidos en un CD ROM, mediante la creación de una anilla en el CD ROM. Para ello se introduce en el CD ROM, en correspondencia con cada uno de los archivos a proteger, uno o más archivos destinados a ser dañados deliberadamente durante el proceso de masterización, mientras se realiza su grabación con el láser, variando la intensidad de éste último, de manera que al intentar volcar los datos del CD ROM, para su copia, la aparición de estos archivos dañados interrumpe la lectura de datos y, consecuentemente, interrumpe e impide la grabación.
