PROBLEM TO BE SOLVED: To quickly check in a PD. SOLUTION: Whether contents data ciphered for an audio server are to be reciphered for a PD 5 or not is decided, and when it is decided that the deciphering of the contents data is unnecessary, contents data corresponding to a track included in a check-out list are read out from an HDD and buffered in a buffer 56 and the buffered contents data are directly copied in the PD 5 via a USB controller and a USB connector 43.
