A recording apparatus includes: a first strategy calculating device (SCD) for calculating a first optimum strategy allowing jitter recorded at a first speed to satisfy a desired condition by adjusting a first standard strategy; a second SCD for calculating a second standard strategy at a second speed by performing clock cycle conversion according to a difference between the first and second speeds on the first standard strategy; a second power calculating device for calculating a second optimum power used at the second speed; a third SCD for calculating a second optimum strategy allowing jitter recorded at the second speed to satisfy a desired condition, by adjusting the second standard strategy; and a fourth SCD for calculating a third optimum strategy at a third speed, based on each of a difference between the first standard and optimum strategies and a difference between the second standard and optimum strategies.
