A distribution server 103 distributes a content via a network, and a KIOSK
terminal 105 receives the content via the network and records the content
in an SD memory card 100. A customer device 111 receives a content via
the SD memory card 100, checks out the content and records a copy on a
recording medium. SD-Audio players 122 to 124 receive a copy of the
content and play back the copy. Here, the KIOSK terminal 105 records a
Usage Rule that certifies the right to control recording of content on
the SD memory card 100. Move Control Information showing the number of
times that moving of rights is permitted is set in the Usage Rule.
