ABSTRACT:
A method for restoring an unused area of a disk using a disk play is provided. The method includes the steps of: erasing the data of an arbitrary track and continuously shifting the data of the next track to the empty track; reforming a UTOC related with the erased and shifted tracks; reforming again track information by combining the last empty track and an unused area after the data is shifted to the last track; and recording the reformed UTOC in the disk. Therefore, the unused area generated due to the limitation of track information provided from the UTOC can be used for re-recording, so that the disk can be used more efficiently.
