Abstract

Se describe un portador de registro para registrar informacion escribiendo marcas en una pista sobre una capa de registro. La marca mas corta utilizada para registrar la informacion tiene una longitud de un numero minimo predefinido d de longitudes del bit de canal. El portador de registro (11) tiene un pre-surco que es modulado por un patron del portador que contiene marcas largas (18, 19) que proporcionan un area de foco (12) en una localizacion predefinida en la capa de registro. Las marcas largas tienen longitudes de por lo menos dos veces la longitud de la marca mas corta para que sean sustancialmente mas largas que el diametro efectivo del punto de exploracion. Un dispositivo de exploracion localiza el area de foco y determina el mejor desplazamiento del foco detectando la amplitud maxima de la senal de lectura mientras que explora el patron del portador.
