Abstract:
1. A method for dynamically partitioning a memory of a recording drive, wherein the memory has a first and second block which at least an optimal recording power record for a first type of recording disk and at least an optimal recording power record for a second type of recording disk are stored respectively, the method comprising: predetermining a ratio of memory spaces of the first and second block; and selecting a method from a first and a second partitioning method to determine the ratio of memory spaces of the first and second blocks when the ratio is not predetermined; wherein the first partitioning method comprises step of determining the ratio of memory spaces of the first and second blocks according to a first predetermined value when a difference between the number of the optimal recording power records for the first type of recording disk and the optimal recording power records for the second type of recording disk reaches the first predetermined value while the second partitioning method comprises step of determining the ratio of memory spaces of the first and second blocks according to a ratio of the optimal recording power records for the first type of recording disk to the optimal recording power records for the second type of recording disk when a total of the optimal recording power records reaches a second predetermined value.
