Abstract

La presente se relaciona con un portador de grabacion comprendiendo marcas de longitud de ejecucion limitadas en una pista. Las longitudes de ejecucion delas marcas representan bits de canal principal y variaciones de otro parámetro de las marcasrep resentando bits de canal secundario. No todas las marcas tienendichas variaciones, solo marcas de al menos una longitud de ejecucion predeterminada tienen dichas variaciones. La presente también se relaciona con undispositivo para codificar, unmétod o para codificar, un dispositivo para decodificar y un método para decodificar.
