Abstract

La invencion es concerniente con un metodo de grabacion de portador de grabacion optico para formar marcaciones y partes planas mediante irradiacion de un haz de radiacion sobre una superficie de grabacion de un portador de grabacion optico, el haz de radiacion para cada marcacion a ser grabada es ajustado a por lo menos un nivel de potencia de escritura (Pw) capaz de formar una marcacion durante un periodo de marcacion (31) y para cada camellon entre las marcaciones a por lo menos un nivel de potencia del fondo (Po) incapaz de formar una marcacion durante un periodo de camellon (32). La invencion tambien es concerniente con un dispositivo de grabacion para efectuar tal metodo. Cuando se graba una senal de bamboleo sobre el portador de grabacion con el fin de obtener una mejor proporcion de senal a ruido de bamboleo durante la escritura, se propone de acuerdo con la invencion que el nivel de potencia intermedio (Po) sea temporalmente elevado a un nivel de potencia intermedio (Pi) durante un periodo intermedio (34). Preferiblemente, el nivel potencia intermedio (Pi) es ajustado dentro de un intervalo de 1.5 a 6, en particular de 2 a 4 veces el nivel de potencia del fondo (Po).
