    摘要: A data management device in a karaoke system which receives a first data file by a receiving unit and is stored in a rewritable memory such as a hard disk. A second data file, recorded on a recording medium such as a CD-ROM, is read out by a reading unit. A file number comparing unit then compares the file numbers of the first and second data file and a file managing unit erases the first data file if the file numbers coincide with each other. In addition, a version comparing unit compares versions of both the first and second data file. If the first data file version is older than the second data file version, then the file managing unit erases the first data file version, so as to ensure that the new version is always used. Furthermore, a detecting unit detects whether data files corresponding to targeted items are recorded in both, the rewritable memory and the recording medium. In the event that data files are recorded in both, the file managing unit erases the data file in the rewritable memory.
