ABSTRACT:
An apparatus for recording information includes an information recording unit which records data on a recording medium having a user data area for recording of user requested data and having a predetermined spare area for reallocating a defect present in the user data area, a data reallocating unit which reallocates data to the predetermined spare area, a temporary spare area recording unit which generates a temporary spare area in a portion of the user data area by copying the reallocated data from the predetermined spare area to the portion of the user data area, and an updating unit which updates the temporary spare area by copying the reallocated data from the predetermined spare area to another portion of the user data area in response to a data change in one of the temporary spare area and the predetermined spare area.
