A method of correcting a step number of a stepping motor in an optical drive is disclosed. After an optical disk is tray into the optical drive, a step number of the stepping motor for moving an optical pickup module by a predetermined number of tracks is firstly calculated. Then, a practical track number by which the optical pickup module is moved after the stepping motor has stepped by the step number is calculated. Thereafter, a corrective track/step ratio is obtained.
