Abstract

PURPOSE:To facilitate history control by providing a history control part and a history recording part in a magnetic disk device. CONSTITUTION:A central processing unit 1 sends an input/output instruction to a magnetic disk control device 2 and the instruction is sent to a magnetic disk device 3. The input/output instruction is decoded by a magnetic disk control part 31, at the time of reading, a magnetic disk access control part 34 is controlled, data designated from a magnetic disk recording part 35 are read, the data are transmitted to the magnetic disk control part 31 and the control is executed so as to send the data to the central processing unit 1. At the time of writing, the data are sent from the magnetic disk control part through the above-mentioned access control part 34 to the magnetic disk recording part 35, simultaneously, controlled by a history control part 32 and a writing address and a writing data are recorded to a history recording part 33. Thus, the history control can be executed without another input output instruction from the central processing unit 1.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明はデータファイルの履歴管理方式に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a data file history management method.

〔従来の技術〕[Conventional technology]

従来、データファイルの動作管理は、磁気テープ装置等
の別記録装置を利用して行っていた。Conventionally, data file operations have been managed using a separate recording device such as a magnetic tape device.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

上述した従来のデータファイルの履歴管理は、別記録装
