Abstract

Un método de ajuste de potencia de escritura hace posible el establecer potencia de escritura óptima con alta precisión. La escritura de ensayo se lleva a cabo mediante el uso de potencia de escritura (Pw,m) (en donde m es un entero) de una pluralidad de clases, y una modulación (M,m) asociada con cada potencia de escritura, se calcula. La potencia óptima asintótica (Pasy-opt) se calcula al desempeñar un cómputo predeterminado mediante el uso de potencia asintótica de referencia (Pasy-ref) y potencia de inicio de escritura de referencia (Pws-ref) que son previamente determinadas para cada medio. Un valor evaluado (S,m=M,m x (Pw,m-Pasy-opt)) se calcula mediante el uso de la potencia asintótica óptima (Pasy-ref) y la potencia de inicio de escritura de referencia (Pws-ref) que son previamente determinadas para cada medio. Un valor evaluado (S,m=M,m x (Pw,m-Pasy-opt) se calcula usando la potencia asintótica óptima (Pasy-opt). La potencia de escritura (Pw) que hace el valor evaluado (S) igual a cero al aplicar aproximación de línea recta a una relación entre la potencia de escritura (Pw,m) y el valor evaluado (S,m), se calcula como potencia óptima de inicio de escritura (Pwsopt). Y la potencia óptima de escritura (Pw-opt) se encuentra al desempeñar un cómputo predeterminado en la potencia óptima de inicio de escritura (Pws-opt).
