Abstract
An optical storage apparatus and a method for eliminating a write power transient thereof are provided. The method includes following steps. First, a target voltage level of a write voltage when next time the optical storage apparatus writes data is obtained. Then, a command value is updated by using the target voltage level according to a relationship between the command value and the write voltage. Next, the write voltage of the optical storage apparatus is pre-charged to the target voltage level according to the updated command value. Thereby, the write power transient of the optical storage apparatus can be eliminated.
