Abstract

La presente se relaciona con un portador de grabacion comprendiendo un patron de pistas substancialmente paralelas para almacenar datos en la forma de marcas, en las cuales los datos son codificados por medio de un codigo de canal. El portador de grabacion también incluye una marca de agua provista mediante el control del parámetro del codigo de canal como para introducir una distribucion de longitud de ejecucion predeterminada en las marcas del portador de grabacion. Las diferencias en el brillo son causadas mediante la introduccion de esta distribucion de longitud de ejecucion. La presente también se relaciona con un dispositivo para leer un portador de grabacion, un método para proveer una marca de agua en el portador de grabacion, y un dispositivo para proveer una marca de agua en un portador de grabacion.
