Abstract

PURPOSE:To improve the time performance of the titled system by copying only a file and file management information registered on a floppy disk. CONSTITUTION:A virtual floppy disk (FD) copying mechanism 2-1 reads out the file information stored in the FD 3 and copies the contents in a main storage device 1. After the copying, the mechanism 2-1 transfers the file management information to a virtual FD memory controlling mechanism 2-2 to determine an address copied in the device 1. After the address determination, the mechanism 2-1 successively reads out files A-C on the FD 3 and copies the files A-C in the device 1 in accordance with the addresses determined by the mechanism 2-2.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は情報処理システムに関し、特に主記憶−装置上
で実現される。仮想フロッピィディスク制御方式に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information processing system, and is particularly implemented on a main memory device. Related to virtual floppy disk control method.

〔従来の技術〕[Conventional technology]

従来、この種の仮想フロッピィディスク制御方式は、フ
ロッピィディスクのポリー−ムイメージ全体を、主記憶
装置上に複写して、制御を行っていた。Conventionally, this type of virtual floppy disk control system has performed control by copying the entire floppy disk's polymer image onto the main storage device.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

しかしながら、上述した従来の仮想フロッピィディスク
制御方式では、フロッピィディスクのボリューム内圧存
在するファイルの容量に関係なく。However, in the conventional virtual floppy disk control method described above, the internal pressure of the floppy disk volume is independent of the capacity of existing files.

フロッピィディスクボリュームイメージで主記憶装置へ
複写を行っているため、ファイル容量が少ないケースに
おいても、ボＩＪ、−ム全体を複写する時間を必要とす
るという次点がある。Since the floppy disk volume image is copied to the main storage device, there is a runner-up problem in that even if the file capacity is small, it takes time to copy the entire volume.
