摘要

An information recording apparatus ( 300 ) transmits identification information (Media ID) of an information recording medium ( 100 ) to an information distributing apparatus ( 200 ). The information distributing apparatus obtains an encryption key (disk key) from the identification information which is sent from the information recording apparatus, and encrypts record information (content). The information distribution apparatus distributes the encrypted record information (encrypted content). The information recording apparatus records the distributed encrypted record information into the information recording medium.
