次に、記憶部340に記録されたコンテンツであってマイディスクに対して記録されていないコンテンツを、マイディスクに対して記録する同期処理について、図9~図11の(a)~(d)を参照して以下に説明する。
記憶部340における領域1の空き容量が少なくなった場合には、領域1に記録されているコンテンツを削除するようにすればよい。領域1に記録されているコンテンツの削除は、ユーザーの指示により実行されるようにしてもよいし、領域1における空き容量が所定値以下となった場合に自動的に実行されるようにしてもよい。
次に、レコーダ装置100におけるコンテンツの再生動作について、図14~図17を参照しつつ以下に説明する。
マイディスクが装填されている場合の再生処理について、図14および図15を参照して以下に説明する。図14は、コンテンツ1~3を記録したディスク1が装填されている場合の記憶部340および記憶部280の状態を示す図である。図15は、マイディスクが装填されている場合において、再生時にコンテンツが読み出される媒体を模式的に示した図である。
続いて、マイディスクが装填されていない場合の再生処理について、図16および図17を参照して以下に説明する。図16は、ドライブ部300に光ディスクが装填されていない場合の記憶部340および記憶部280の状態を示す図である。図17は、マイディスクが装填されていない場合において、再生時にコンテンツが読み出される媒体を模式的に示した図である。

次に、マイディスクの登録解除処理について説明する。ユーザーからのディスク1の登録解除指示を受けたドライブ制御部320は、記憶部340において記録されている、登録を解除するディスク1に対応付けられた領域を管理する管理情報を消去する。すなわち、エントリにおけるメディアID情報、メディアキー情報およびマップ情報を削除すると共に、割り当てフラグを、割り当てが行われていないことを示す「0」に変更する。また、領域にデータが記録されている場合には、記録されているデータも消去する。これによって、記憶部340におけるエントリは、新たなマイディスクの登録が可能な状態となる。
レコーダ装置100では、マイディスクとして登録されている光ディスクへのデータの書き込みおよび光ディスクからのデータの読み出しには、マイディスクとして登録されている光ディスクから取得したファイルシステムを用いることが好ましい。
最後に、レコーダ装置100に接続された表示装置におけるコンテンツとタイトルリストに記録されている情報との表示例について、図22を参照しつつ以下に説明する。図22は、表示装置500上でのコンテンツおよびタイトルリストに記録されている情報の表示を概略的に示す図である。
