Abstract
Se describe un metodo y un dispositivo para la escritura de marcas de datos en un disco optico o un disco maestro, las marcas de datos seran situadas a lo largo al menos de una metapista, la cual es formada por un numero de subpistas paralelas coplanares. El metodo comprende una etapa de superposicion del movimiento rotacional y el movimiento radial del disco y de un punto luminoso de escritura sobre el disco entre si. El movimiento radial comprende un componente de movimiento en una primera direccion radial, y saltos repetidos en forma periodica en una segunda direccion radial opuesta a la primera direccion radial. El movimiento radial es una superposicion de: a) un primer componente de movimiento radial (18), a traves del cual la posicion radial del punto luminoso de escritura como una funcion de la posicion angular con respecto al movimiento rotacional es cambiada en forma ventajosa con una primera inclinacion, y b) un segundo componente de movimiento radial (20) periodico, un periodo del cual, graficado como una funcion de la posicion angular, es dividido en: aa) un primer intervalo (20.1), en el cual la posicion radial del punto luminoso de escritura cambia con una segunda inclinacion, ya sea en la direccion radial del primer componente de movimiento radial o en la direccion radial opuesta al mismo, y bb) un segundo intervalo adyacente (20.2), en el cual la posicion radial del punto luminoso de escritura sobre el disco cambia en una direccion radial opuesta a la direccion de la superposicion del primer (18) y del segundo componentes de movimiento radial durante el primer intervalo (20.1) y can una tercera inclinacion que tiene una cantidad mas grande que la cantidad de la suma de la primera y la segunda inclinaciones. Tambien se describe un disco optico o un disco maestro producido por el metodo de la invencion.
