Abstract

　コンテンツ情報（ＣＩ）を記録し、その後暗号キーを含む制御情報（ＳＩ）を記録する。コンテンツ情報（ＣＩ）を書込む領域は、再生専用型ディスクにおいてユーザ領域（ＵＩＡ）に対してシフトさせたものとする。制御情報（ＳＩ）の書き込みの際も同じだけシフトさせる。シフトの結果、再生専用型ディスクにおいて制御情報の記録される領域（ＳＩＡ）には、コンテンツ情報（ＣＩ）またはダミーデータ（ＤＤ）が書き込まれるようにする。シフトの値を示す情報は、ランダムに選択され、ディスクが記録装置から取り出されるときに破棄される。暗号化されたコンテンツを記録型光ディスクへダウンロード記録するに際して、正しく１回だけ完全なコンテンツをディスクに記録することが可能となる。
