A data encryption processor (12) encrypts a data set received from a controller (11) in accordance with a predetermined encryption algorithm, and generates a data set in which encrypted data C is inserted into a data area, and encrypted data B is inserted into a padding area. The data encryption processor (12) passes the encrypted data set to a data recording processor (13). The data recording processor (13) records the data set passed from the data encryption processor (12) in a data recording unit (14) under the control of the controller (11). |
