Abstract
A technique of the present invention includes a storage section for storing contents data and an encryption flag indicating that any one of an encryption recording mode and a non-encryption recording mode is set, an encrypting engine for encrypting contents data using an encryption key when the encryption recording mode is set, and a control section for controlling a storage section so that the encryption key and the encrypted contents data are stored when the encryption recording mode is set. Further, when the setting is changed from the encryption recording mode into the non-encryption recording mode, the control section controls the storage section so that the encryption flag is changed to indicate the setting of the non-encryption recording mode with the continuous storage of the encryption key.
