ABSTRACT:
An optical disc recording/reproducing apparatus detects last position information of already recorded data and information of initial data recordable capacity of an optical disc that is in a state of no further writing by a recording completion process, a calculating device that calculates data recordable capacity of a free space in accordance with the last position information of already recorded data and the information of initial data recordable capacity of the optical disc and records data in the free space after the last position of already recorded data. The optical disc recording/reproducing apparatus scans the area after the last position of the already recorded data, and when the recorded data is found in the area, the data recorded after the last position is read. Data can be recorded to or reproduced from a free space of the optical disc to which the finalizing process has been executed.
