Patent ID: 7265782

Claim:
A data recording device comprising: a memory which stores data files; a selection unit which selects one of the data files stored in the memory; an instruction unit which issues an instruction at an arbitrary timing to relate audio data to the selected data file; a first determination unit which determines whether the instruction unit has issued the instruction to relate the audio data to the selected file; a second determination unit which determines whether the selected data file is a kind of data file to which audio data is not permitted to be related, when the first determination unit determines that the instruction unit has issued the instruction; an inhibiting unit which inhibits the audio data from being related to the selected data file when the second determination unit determines that the selected data file is the kind of data file to which audio data is not permitted to be related; a notifying unit which performs a first notification operation when the second determination unit determines that the selected data file is the kind of data file to which audio data is not permitted to be related; a third determination unit which determines whether audio data is already related to the selected data file when the second determination unit determines that the selected data file is a kind of data file to which audio data is permitted to be related; and a control unit which executes processing to relate the audio data to the selected data file when the third determination unit determines that audio data is not already related to the selected data file; wherein the notifying unit performs a second notification operation, which is different from the first notification operation, when the third determination unit determines that audio data is already related to the selected data file.
