ＣＲＣ等が記録される。Each sector SC is separated from adjacent sectors by a gap G. Each sector SC is itself divided by a gap G into a header section H and a data section. The data section records data to be stored, error correction codes, etc., and the header section H records identification information of the data recorded in the data section, ie, sector address, CRC, etc.
ヘッダ部への書込は、光デイスク板を作製する段設で、
プレグルーブとともに書込が行なわれる場合もあるし、
データ書込時に、データとともに書ぎこむ場合もある。Writing to the header is done in stages when making the optical disk board.
In some cases, writing is performed along with the pregroove,
When writing data, it may be written along with the data.
いずれにせよ、データ部、ヘッダ部とも、一度書と込み

が記録されているのか、どのセクターが欠陥セクターで
あるのか、あるいは、未記録部分の先頭のセクターアド
レスは何か等の情報を管理する必要がある。Now, when using an optical disk as a storage device, it is important to know the information recorded on each optical disk, that is, what kind of data is recorded, which sector is a defective sector, or the beginning of an unrecorded part. It is necessary to manage information such as what the sector address is.
従来、このような情報管理は、専用のフロッピーディス
ク等、再書込可能な記憶媒体を用いて行っていた。Conventionally, such information management has been performed using a rewritable storage medium such as a dedicated floppy disk.
しかし、各光ディスクの情報を、専用の記憶媒体に記憶
させるのは面倒である。又、記憶装置を大容量ファイル
として使用する場合に、記憶内容の体系や配列を変える
場合、フロッピーディスク等の記憶媒体の内容を再編成
するのは容易でない。However, it is troublesome to store the information of each optical disc in a dedicated storage medium. Furthermore, when a storage device is used as a large-capacity file, it is not easy to rearrange the contents of a storage medium such as a floppy disk when changing the system or arrangement of storage contents.
