To prevent the erasing of the music pieces the user desires, when automatically erasing a broadcast data file.

When erasing a broadcast data file, the music data matching the keyword are extracted from the broadcast data file and stored as a broadcast music file on the HDD14, if the proper music file of the music pieces matching the keyword is not recorded on the HDD14. Thus, the music pieces desired by the user are not erased by registering them as the keyword. Meanwhile, when the proper music file of the music matching the keyword is already recorded on the HDD14, it is simply reproduced without storing the broadcast music file, thus the music pieces matching the keyword are not extracted from the broadcast data file to record on the HDD14 as the broadcast music file.
