Abstract

PURPOSE:To improve the operability of a titled system, by converting positional information of data of each tape into positional information of data of an integrated tape and installing the converted positional information to the leading edge of the integrated tape, when plural magnetic tapes are integrated in one tape. CONSTITUTION:When plural magnetic tapes T containing the positional information of data 1 and data 2, 2,- are integrated in one magnetic tape T', the positional information 1 of the data of each tape is converted into the positional information 5 of the integrated tape T' and, at the same time, the positional information 5 is gathered to the leading edge of the integrated tape T' and recorded. The data 2 of each tape T are stored next to the positional information 5 as data groups 6, 6,-. Therefore, the data of the integrated tape T' can be handled easily by means of the positional information of the integrated tape T' only and the utilizing efficiency of the tape can be improved.

Description

【発明の詳細な説明】 〔発明の利用分野〕 本発明は、磁気テープ上のデータの位置情報の制御方式
に係り、特に複数の磁気テープを統合した場合の制御に
好適なデータの統合構成制御方式に関する。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a method for controlling position information of data on a magnetic tape, and in particular, data integration configuration control suitable for control when a plurality of magnetic tapes are integrated. Regarding the method.

〔発明の背景〕[Background of the invention]

従来、磁気テープ上のデータの位置情報は該当する磁気
テープ上でのみ有効であるため、これら磁気テープを統
合した場合統合すべき磁気テープ上でのデータの位置は
移動するがデータの位置情報は変換されず、磁気テープ
の統合によりデータの位置情報を使用することができな
いという欠陥があった。Conventionally, data position information on a magnetic tape is valid only on the corresponding magnetic tape, so when these magnetic tapes are integrated, the data position on the magnetic tape to be integrated moves, but the data position information is There was a defect that the data location information could not be used due to the integration of magnetic tape.

〔発明の目的〕[Purpose of the invention]

本発明の目的は、複数の磁気テープを統合した場合磁気
テープ上のデータの位置情報を統合すべき磁気テープの
データの位置に合わせて変換し、磁気テープの先頭に位
置させ操作性の良いデータの位置情報を提供することに
ある。An object of the present invention is to convert the positional information of data on the magnetic tapes according to the position of the data on the magnetic tapes to be integrated when a plurality of magnetic tapes are integrated, and to position the data at the beginning of the magnetic tapes so that the data can be easily manipulated. The goal is to provide location information.

〔発明の概要〕[Summary of the invention]

本発明は、データの位置情報を統合すべき磁気テープの
データ位置に合わせ変換し、磁気テープの先頭にデータ
の位置情報を設は操作性の容易さを図るようにしたもの
である。In the present invention, the data position information is converted to match the data position of the magnetic tape to be integrated, and the data position information is set at the beginning of the magnetic tape for ease of operation.

〔発明の実施例〕[Embodiments of the invention]

以下、本発明の一実施例を第１図、第２図により説明す
る。本実施例では、単独の磁気テープでデータの位置情
報を保持しているものを一本の磁気テープに複数統合す
ることを対象とする。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In this embodiment, a plurality of individual magnetic tapes holding data position information are integrated into one magnetic tape.

磁気テープ上のデータの位置情報は磁気テープ上のデー
タの位置を保持しているが（第１図の１）これは自磁気
テープでのみ有効である。The data position information on the magnetic tape holds the position of the data on the magnetic tape (1 in FIG. 1), but this is valid only for the own magnetic tape.

このため複数の磁気テープをただ単に統合した場合は、
統合したデータの位置情報を変換できず、磁気テープ上
のデータの取り扱いが非常に困難である（第１図の２）
。このため統合した磁気テープ上での位置情報に変換し
、かつ磁気テープの先頭にデータの位置情報を格納する
ことにより、データの位置情報のみで容易に統合した磁
気テープのデータの取扱ができる（第１図の６）。第２
図は第１図の６を実施する方法について説明している。Therefore, if you simply integrate multiple magnetic tapes,
The position information of the integrated data cannot be converted, making it extremely difficult to handle data on magnetic tape (2 in Figure 1).
. Therefore, by converting the data into position information on the integrated magnetic tape and storing the data position information at the beginning of the magnetic tape, it is possible to easily handle the data on the integrated magnetic tape using only the data position information ( 6) in Figure 1. Second
The figure describes a method for implementing 6 of FIG.

本実施例によれば操作性の向上に効果がある。This embodiment is effective in improving operability.

〔発明の効果〕 本発明によれば、単独の磁気テープ上のデータの位置情

使用効率の向上が図られ、経済性に富みかつ操作が簡略
化されるという効果がある。[Effects of the Invention] According to the present invention, it is possible to use the position information of data on a single magnetic tape and the position information of data on magnetic tapes integrated through the same interface. The present invention has the advantage of being able to be integrated into other magnetic tapes, improving the efficiency of using magnetic tapes, being economical, and simplifying operations.
