Abstract

Un portador de grabacion para recodificar informacion mediante la escritura de marcas en una pista que tiene una capa de grabacion con un pre-surco (51). El pre-surco tiene una oscilacion que tiene modulacion de oscilacion (52) para la representacion de informacion de control. El pre-surco ademas tiene una modulacion de pre-surco constituida por areas de hendiduras de pre-surco (54) que tienen una amplitud y profundidad predefinida que se alternan con areas de contacto de pre-surco (53) que tienen una amplitud y/o profundidad reducida, en particular profundidad cero. La mayor parte de las areas de contacto (53) se localizan en los cruces en cero de la oscilacion y la mayor parte de las areas de hendiduras de pre-surco se localizan en los valores pico de la oscilacion para la optimizacion de la potencia de la senal de oscilacion. Un dispositivo de barrido cuenta con medios de deteccion de oscilacion para la recuperacion de la informacion de control de la modulacion de oscilacion, y medios de desmodulacion de pre-surco para la recuperacion de informacion de control de grabacion de la modulacion de pre-surco.
