A power control method is provided for an optical disk drive. The optical disk drive has an optical read/write module for accessing an optical storage media. The power control method includes the following steps: measuring the temperature of the optical read/write module; predicting a threshold current of the optical read/write module according to the temperature; determine the accessing mode of the optical storage media; measuring the output power of the optical read/write module; computing a first current required for the optical read/write module according to the output power of the optical read/write module and a base power in the accessing mode; compensating the computed first current according to the predicted threshold current; and driving the optical read/write module according to the first current.
