- ユーザデータが記録されるボリューム空間と、前記ボリューム空間に含まれる欠陥領域の代わりに使用され得る交替領域を含むスペア領域と、前記欠陥領域を管理するための欠陥管理情報が記録される欠陥管理情報領域とを備えた情報記録媒体に対して記録動作および再生動作の少なくとも一方を行うドライブ装置であって、
前記欠陥管理情報が、複数のDFLエントリを含み、各DFLエントリは、前記欠陥領域の位置を示す欠陥位置情報と、前記交替領域の位置を示す交替位置情報と、当該DFLエントリの属性を示す欠陥状態情報とを格納するフィールドを含み、
記録命令または再生命令を受け取ると、記録または再生の動作が要求される領域が前記DFLエントリで示される領域であって、当該DFLエントリの属性が、欠陥が解消されたか否かに関わらず当該欠陥領域及び当該交替領域のいずれにも有意なユーザデータは存在しない旨を示す属性であるかどうかを判定する判定部と、
前記判定部の判定結果に基づいて前記記録または再生動作がダミーデータの使用を含むか否かの処理内容とする決定を行う決定部とを備えたことを特徴とする、ドライブ装置。 - 記録命令を受け取り、記録が要求されるセクタを包含するクラスタにおいて先頭に記録要求の範囲に含まれない端数のセクタがあり、かつ、前記判定部がその先頭セクタを含むクラスタが欠陥領域及び交替領域のいずれにも有意なユーザデータは存在しない旨を示す属性を持つDFLエントリとして登録されていると判定した場合、前記決定部は、ダミーデータで前記端数のセクタに対応するデータバッファを埋める処理内容とする、請求項1に記載のドライブ装置。
- 記録命令を受け取り、記録が要求されるセクタを包含するクラスタにおいて最後に記録要求の範囲に含まれない端数のセクタがあり、かつ、前記判定部がその最終セクタを含むクラスタが欠陥領域及び交替領域のいずれにも有意なユーザデータは存在しない旨を示す属性を持つDFLエントリとして登録されていると判定した場合、前記決定部は、ダミーデータで前記端数のセクタに対応するデータバッファを埋める処理内容とする、請求項1に記載のドライブ装置。
- 再生命令を受け取り、前記判定部が再生が要求されるセクタを含むクラスタが欠陥領域及び交替領域のいずれにも有意なユーザデータは存在しない旨を示す属性であると判定した場合、前記決定部はダミーデータを生成する処理内容とする、請求項1に記載のドライブ装置。
- 請求項1に記載のドライブ装置と、前記ドライブ装置に対して記録命令または再生命令を行う上位制御装置とを備えた、システム。
