Abstract

Un método de grabación de portador de grabación óptico para formar marcas y pasos mediante la irradiación de un haz de radiación en una superficie de grabación de un portador de grabación óptico, el haz de radiación para cada marca a ser grabada siendo fijado en al menos un nivel de energía de escritura (Pw) capaz de formar una marca durante un período de marca y para cada paso entre las marcas en al menos un nivel de energía inferior (P0) incapaz de formar una marca durante un período de paso. La invención también se relaciona con un dispositivo de grabación para llevar a cabo tal método. Cuando se graba una senal de fluctuación en el portador de grabación, para obtener una mejor proporción de senal -a-ruido de la senal de fluctuación, se propone, de acuerdo con la invención, que el nivel de energía inferior (P0) se eleve temporalmente a un nivel de energía intermedia (Pi) durante un período intermedio. Preferentemente, dicho nivel de energía intermedio (Pi) s fijado dentro de un rango desde 1.5 a 6 en particular de 2 a 4, veces el nivel de energía inferior (P0).
