Abstract: The invention is to provide a method for determining an optimum writing strategy for an optical disk drive to record data onto a recordable optical disk. According to a preferred embodiment of the method of the invention, a pre-stored third type datum is retrieved from the recordable optical disk. Then, a step of judgment is performed to judge if the third type datum matches one of the plurality of first type data stored in the optical disk drive, and each of the plurality of first type data maps one of the first writing strategies. If the result is NO, a second writing strategy, of which the mapped second type datum matches the third type datum, is loaded from a remote server, and the loaded second writing strategy is determined as the optimum writing strategy.
