The file generating part 3 divides the digital stream data 21 into a plurality of data files and records them as a plurality of data files into the recording medium 5. The file number obtaining part 7 obtains the number of the data files that are managed by at least one management file among the management files that are already recorded in the recording medium 5. After the file generating part 3 records plural sets of the digital data, the management file judging part 6 a determines a management file for storing the management information by comparing a sum of the number of the plurality of the recorded data files and the number of the data files that are managed by the management file obtained by the file number obtaining part 7 with the maximum data file number L. The management information generating part 4 adds the management information of the plurality of the data files into the management file that is determined by the management file judging part 6 a.
In the present embodiment, structures of directories for recording the management file and the data file are similar to the directories of Embodiment 3 described above. That is, the management-file directory and the data-file directory are provided, respectively. The present embodiment will provide a case where a directory structure of the recording medium 5 is the same as the directory structure shown in FIG. 10.
Next, an example of an operation of the data recording system 1 b for dividing and recording the digital stream data 21 will be explained. FIG. 17 is a flow chart showing an example of the operation of the data recording system 1 b.
In Step S301, the dividing part 102 reads the digital stream data 21 via the data input terminal 101, and records it as the data file into the temporary turnout area 108. In the case where the size of the digital stream data 21 exceeds the predetermined maximum file size, the dividing part 102 divides the digital stream data 21 into a plurality (J) of data files having a size that is equal to or less than the predetermined maximum file size, and records them into the temporary turnout area 108.
