<p>A data storage apparatus (63), which can format a recording medium (11) in the background, that verifies data written in a designated region of the recording medium (11) if the designated region has not yet been certified in the background, and writes the data in an alterative region of the recording medium if the designated region is found defective. Since the data storage apparatus either certifies the designated region of the recording medium (11) or verifies the data written in the designated region, the data storage apparatus can enhance the reliability of the data written in the recording medium (11), but the data storage apparatus does not waste time by verifying the designated region of the recording medium (11) two times or more. <IMAGE></p> |
