An optical disk device includes an optical pickup, and a controller. The optical pickup emits light on an optical disk, and detects return light from the optical disk. The controller performs a focus control based on a focus error signal corresponding to the return light detected by the optical pickup, and performs a tracking control based on a tracking error signal corresponding to the return light detected by the optical pickup. The controller finds a relation of an amount of deviation in a tracking balance of the tracking error signal relative to a change in a focus balance of the focus error signal while the tracking control is stopped prior to reproduction of the optical disk. The controller corrects the deviation in the tracking balance attributable to the change in the focus balance based on the relation while the focus balance is adjusted.
