Abstract

Un dispositivo para la grabacion de informacion escribe y da lectura a las marcas y espacios, cada uno de los cuales tiene una longitud nominal de pasada. La potencia de una fuente de radiacion es controlada para la escritura de las marcas y espacios de acuerdo con un patron de potencia en funcion de la longitud de pasada. El patron de potencia para una marca de una longitud larga de pasada comprende al menos tres impulsos que tienen una potencia de escritura 65, al menos un primer periodo intermedio entre los impulsos que tienen una potencia de polarizacion 66 y al menos un segundo periodo intermedio entre los impulsos que tienen una potencia reducida de polarizacion 70, por lo menos un segundo periodo intermedio incluye el periodo intermedio antes del impulso final del patron de potencia. Debido a la potencia reducida de polarizacion, es reducido el calentamiento previo en el inicio de una siguiente marca despues de una marca larga y un espacio.
