PROBLEM TO BE SOLVED: To move contents without trouble and with high security. SOLUTION: Music are copied from two CDs into a hard disk drive as a storage device. A track management file 201F is created from the information being reproduced and outputted from the CDs. A part of the stored music is moved into a memory card 40a. The history of this move is created on a management file 203F by using identification information. Then, when the music is returned to the hard disk from the memory card, the identification information of the data to be returned is collated with that in the move history management file. When it is detected that both information are identical, it is judged as returning of the data. In such a case, the data are returned to the same position as the original one in the hard disk drive. As a result, the hard disk drive stores the music in the same order as that in the hard disk drive 201a. |
