A METHOD OF OVERWRITING DATA IN A WRITE-ONCE INFORMATION STORAGE MEDIUM (300) AND A DATA RECORDING AND/OR REPRODUCING APPARATUS (500) THEREFOR. IN THE DATA OVERWRITING METHOD, A COMMAND TO OVERWRITE NEW DATA IN A FIRST AREA OF THE WRITE-ONCE INFORMATION STORAGE MEDIUM WHERE DATA HAS ALREADY BEEN RECORDED IS ISSUED. THEN, THE FIRST AREA IS CONSIDERED AS A DEFECTIVE AREA, AND THE NEW DATA IS RECORDED IN A SECOND AREA. THEREAFTER, UPDATED DEFECT MANAGEMENT INFORMATION, INCLUDING INFORMATION ABOUT THE LOCATIONS OF THE FIRST AND SECOND AREAS, IS RECORDED IN THE WRITE-ONCE INFORMATION STORAGE MEDIUM. ACCORDINGLY, OVERWRITING CAN BE PERFORMED IN WRITE-ONCE INFORMATION STORAGE MEDIA, WHICH IS INCAPABLE OF PHYSICAL OVERWRITING, BY USING A LOGICAL OVERWRITING TECHNIQUE. THUS, DATA RECORDED IN THE WRITE-ONCE INFORMATION STORAGE MEDIUM MAY BE CHANGED OR UPDATED.
