Abstract: <P>PROBLEM TO BE SOLVED: To provide a disk recorder capable of easily restoring deleted data.  <P>SOLUTION: When data are recorded on a disk but a recording area is insufficient (YES in S25), a program title list of a deleted program data file specified as non-reproductive in the recording area is displayed (S33). A user looks at the display of the list and performs external input operation to select a desired file (S39, S43). The selected program data file is deleted from the recording area of the disk (S45). Thus, a recording area is secured. Moreover, when the user inputs designation release of the non-reproductive state by external operation concerning the deleted program data file, the file is restored to the original reproducible state. Since the restoration is done only by releasing the designation and is not accompanied by file movement, a load on the recorder can be suppressed at the time of this restoration.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
