Write strategy setting apparatus utilizing shared storage unit and method thereof

Abstract

A write strategy setting apparatus applied in an optical disc drive includes a storage unit, an error calculator, and a write strategy controller. The storage unit stores an initial write strategy including a plurality of write strategy parameter sets corresponding to a plurality of data set types; the error calculator calculates an error value set for each data set type generated by the optical disc drive utilizing a corresponding write strategy parameter set in the initial write strategy, and stores the calculated error value set into the storage unit to thereby overwrite the write strategy parameter set; and the write strategy controller determines a modified write strategy by referring to a plurality of error value sets stored in the storage unit and the initial write strategy, and then storing the modified write strategy into the storage unit.
