In an optical disk recorder ( 1 ), when a user instruct to format an optical disc ( 2 ), a main control unit 3 reads out file management data from a file management data area of the optical disc ( 2 ), and writes the read file management data at a specific area of the optical disc ( 2 ) through an optical head ( 6 ) so as to save the read file management data. When the user instruct to cancel the formatting of the optical disc ( 2 ), the main control unit ( 3 ) reads out the saved file management data from the optical disc ( 2 ) and rewrite the saved file management data into the original file management data area again. Thereby, the user can use the user data recorded before the formatting of the optical disc ( 2 ).
