An optical disc on which data is recorded and/or from which the data is reproduced, includes a recording area where the data is recorded in at least one physical cluster, a defective area, where a defect that prevents a recording and/or reproduction of data is present, provided in the recording area, and a recording end area where information indicating an end of recording is recorded before the defective area. A method of recording data on and/or reproducing the data from a high density optical disc having a defective area, includes recording the data in a predetermined recording area having the defective area, and recording end data indicating an end of the recording before the defective area.
