Abstract

PURPOSE:To prevent an illegal copy by incorporating a ROM in a floppy disk medium, storing a key work, etc., and unabling the copy of the data only. CONSTITUTION:A ROM 30 is incorporated on a floppy disk medium 3 and the key word necessary for using the data is stored in this ROM. A host device 1 reads the key word from the ROM 30 via the interface circuit 20 of a floppy disk device 2 to make the medium 3 usable. Consequently it is useless to copy the data on the floppy disk medium having the ROM storing the other key word and an illegal copy is prevented.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、情報処理システム等に搭載されるフロッピィ
ディスクシステムに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floppy disk system installed in an information processing system or the like.

〔従来の技術〕[Conventional technology]

従来、この種のフロッピ１デイスクシステムでは、フロ

有している。The floppy disk system of the present invention includes a floppy disk medium that is externally readable and has a built-in ROM that stores information for using data stored on a magnetic storage surface, and a floppy disk that is readable from the outside and has a built-in ROM that stores information for using data stored on a magnetic storage surface. The computer has a floppy disk device with a built-in interface circuit that reads data stored in the computer and sends it to a host device.

〔実施例〕〔Example〕

次に、本発明の実施例について図面を参照して説明する
。Next, embodiments of the present invention will be described with reference to the drawings.

第１図は本発明のフロンビイディスクシステムの一実施
