Abstract
Un portador de grabación para grabar información mediante la escritura de marcas en una pista posee una capa de grabación con una pre-acanaladura (51). La pre-acanaladura posee una fluctuación que tiene modulación de fluctuación (52) para representar información de control. Además, la pre-acanaladura tiene una modulación de pre -acanaladura constituida por áreas de surco de pre-acanaladura (54) que poseen una profundidad y un ancho predefinidos alternándose con áreas de paso de pre-acanaladura (53) teniendo una profundidad y/o ancho reducidos, en particular una profundidad cero. Una mayoría de las áreas de paso de pre-acanaladura (53) se encuentra localizada en cruces cero de la fluctuación y una mayoría de lsa áreas de surco de pre-acanaladura se encuentran localizadas en valores pico de fluctuación para optimizar la fuerza de la senal de fluctuación. Un dispositivo de exploración posee medios de detección de fluctuación para recuperar la información de control de la modulación de fluctuación, y medios de desmodulación de pre-acanaladura para recuperar la información de control de grabación de la modulación de la pre-acanaladura.
