<p>A revocation list is registered a public ROM area (132). The revocation list designates at least one electronic device in which use of the storage medium (13) by the designated electronic device is to be revoked. A controller (130) receives from the electronic device (LCM or PD) which attempts to access, identification information indicative of the electronic device (LCM or PD), and checks whether identification information corresponding to the received identification information is contained in the revocation list, thereby determining whether or not use of the storage medium (13) by the electronic device (LCM or PD) which attempts to access should be revoked. <IMAGE></p>
