Abstract
【解決手段】 データ領域に記録されたデータを読み取る読み取り部と、ディスクのディスク管理領域から欠陥に関する位置情報を含むDFLとDFLに関する位置情報を含むDDSとを読み取り、DFLを用いてディスクのデータ領域に記録されたユーザデータを読み取るように読み取り部を制御する制御部とを含み、DFLは、ディスクの第1の領域に最後に記録された臨時欠陥情報の複写であって、ディスクのファイナライジング時に記録され、DDSは、ディスクの第2の領域に最後の記録された臨時欠陥情報の位置情報を含む臨時欠陥管理情報の複写であり、ディスクのファイナライジング時に記録されることを特徴とする。

Description
前記情報記録媒体のディスク管理領域から欠陥に関する位置情報を含むDFLと前記DFLに関する位置情報を含むDDSとを再生し、前記DFLを用いて前記情報記録媒体のデータ領域に記録されたユーザデータを再生し、前記DFLは、前記ディスクの第1の領域に最後に記録された臨時欠陥情報の複写であって、前記ディスクのファイナライジング時に記録され、前記DDSは、前記ディスクの第2の領域に最後の記録された前記臨時欠陥情報の位置情報を含む臨時欠陥管理情報の複写であり、前記ディスクのファイナライジング時に記録されることを特徴とする。
iを付与すれば、以後に欠陥が発生している部分を記録した後にここに付与されるLSNは、残りのデータに付与されたLSNより以前のLSNi−1を付与してこそ、再生時にデータが順に再生され得る。しかし、LSNが順次に付与されずに、その順序が入れかわる区間が生じれば、論理セクタ管理が容易ではないため、本実施例では、欠陥が発生している部分の以後のデータが記録された領域は、何れも欠陥領域として編入させることで、論理セクタ管理の効率を向上させた。
