本発明は光ディスク管理方式に関し、特にファイル形式
に重点のある光ディスク管理方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an optical disc management system, and particularly to an optical disc management system that places emphasis on file format.
従来、この種の光ディスク管理方式は、第2図に見るよ

の領域に分かれていた。Conventionally, this type of optical disc management system has data sections 13a, 13b, . . . on an optical disc medium, as shown in FIG.
and an index section 12 that stores the information of the data section.
It was divided into three areas: a collection of files 11a, 12b, . . . , and an auxiliary record section 11a, llb, .
従って、第3図を見るに従来の光ディスク管理方式で補
助レコード部・索引部・データ部の3つの領域に分かれ

タ部の読み出し書き込み時間26の時間がかかる。Therefore, as shown in Figure 3, when the conventional optical disc management system is divided into three areas: auxiliary record section, index section, and data section, the head movement time to the auxiliary record section is 2.
1. It takes time to read and write the auxiliary record section 22, time to move the head to the index section 23, time to read and write the index section 24, time to move the head to the data section 25, and time to read and write the data section 26. .
上述した従来の光ディスク管理方式は、データ部と前記
データ部の情報を格納する索引部とかはなれている為、
データの読み込み又は書き込む際、データ部の情報を格
納する索引部を読み込み又は書き込んだ後、データ部を
読み込み又は書き込むため、データ部へ移動する時間が
加算され、データの読み込み又は書き込みの時間が遅く
なるという欠点がある。In the conventional optical disc management method described above, the data section and the index section that stores information in the data section are separated, so
When reading or writing data, after reading or writing the index section that stores information in the data section, the time required to move to the data section is added to read or write the data section, which slows down the time for reading or writing data. It has the disadvantage of becoming.
本発明の光ディスク管理方式は、光ディスク媒体上に、
データ部と、前記データ部を連続した領域に前記データ
部の情報を格納する索引部と、前記光ディスク媒体に格
納されている全ファイルのファイル名および前記索引部

。The optical disc management method of the present invention includes, on an optical disc medium,
a data section; an index section that stores information of the data section in an area continuous with the data section; and an auxiliary record section that stores the file names of all files stored on the optical disk medium and the position of the index section. It is composed of:
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

Total processing time when divided into three areas, and total processing time when an auxiliary record section, an index section, and an area data section that is continuous with the index section are created using the control method of the optical disc management system implementing the present invention. is shown.

The present invention is a control method of an optical disc management system, in which an auxiliary record section, an index section, and the index section are displayed in a continuous area. When the data section is created, the head movement time to the auxiliary record section 31, the auxiliary record section read/write time 32, the head movement time to the index section 33, the index section read/write time 34, It takes 35 hours to read and write the data section.

きるという効果がある。As explained above, the present invention stores a data section on an optical disk medium, and information of the data section is stored in an area continuous with the data section. By creating an index section, the time required to move the head to the data section due to the separation between the index section and the data section is not added to the time for reading or writing data in the optical disk management system. This has the effect of speeding up the writing time.
