Abstract
Procedimiento de grabación y lectura de CD-ROM para evitar su copia. Se realiza la grabación con láser de los ficheros de la aplicación mediante un proceso convencional de mastering, se graban al menos dos tramos (T1, T2) de ficheros en los cuales no existe ningún fichero de la aplicación y entre los cuales debe existir al menos un fichero a la aplicación, se graban una pluralidad de ficheros de complemento de modo que la grabación total supera el tiempo total de grabación previsto en los discos vírgenes disponibles en el mercado, se efectúan unas marcas láser (Ml-M3) mediante sobreescritura en los ficheros dispuestos en tramos (Tl,T2) siendo estas marcas ilegibles para el lector CD-ROM. Se caracteriza porque en los ficheros en tramos (T1, T2) se graba al menos un fichero parcialmente bloqueado (FPB) en el que se incluye al menos un código (5) de 80 bits. También comprende un procedimiento de lectura en el que se incluye un programa distinto de la aplicación para verificar el código (5) y en caso de que se falso abortar la ejecución de la aplicación.
