The present invention provides a method of managing a defective area of an optical disc recordable at high speed, recording/reproducing method thereof, and recording/reproducing apparatus thereof, by which an accurate decision of the defective area is provided. Moreover, as optimal recording speed is applicable to re-recording in a specific section, thereby enabling to secure high reliance of data. In an optical disc provided with a defect management area for defect management within a high-speed recordable disc, the present invention includes verifying whether the defective area is generated in performing a recording at high speed, re-verifying presence or non-presence of defect of a corresponding area by changing a recording speed into low speed if the defective area is generated at the high speed, and recording to manage in the defect management area a location information of an area decided as the defective area at the high speed but as a non-defective area at the low speed.
