摘要：
A storage system having a plurality of optical disc devices allows other optical disc devices inside the storage system to reproduce the optical disc recorded by a certain optical disc device but inhibits optical disc devices outside the storage system to reproduce the optical disc. A device key as a base for generating an encryption key is common to the plurality of optical disc devices. In the optical disc devices, a guest key other than the device key can be used temporarily to generate the encryption key. An authentication list containing a reproduction condition is recorded with the key information to the optical disc.
