    Abstract: An optical disc apparatus may write information to an optical disc by forming a mark and a space on the optical disc. The optical disc apparatus may include a write stopping unit, a deviation calculating unit, and a write strategy correction unit. The write stopping unit may temporarily stop writing of information to the optical disc at a predetermined time. The deviation calculating unit may obtain a deviation value of written information just before writing of information is stopped by the write stopping unit. The write strategy correcting unit may correct a write strategy based on the deviation and the previously-stored inherent variation. Writing of information to the optical disc may be restarted using the corrected write strategy.
