摘要：
An encryptor is provided for encrypting AV data sent from an interface. A controller controls recording of the encrypted AV data by controlling a recorder for recording the encrypted AV data in a magnetic disk. The recorder is controlled by the controller so as to reproduce the data recorded on the disk. A decrypter decrypts the reproduced data that is sent to the interface.
