<p>PURPOSE:To prevent mis-copying and the damage of a master medium at the time of insertion from being generated by eliminating an operation to insert the master medium to a floppy disk drive at every copying. CONSTITUTION:Data in the master medium 1 is registered from the floppy disk drive 2 to a magnetic tape 6 by operating a keyboard 5 after attaching a code number. A host computer 3 stores the data in a corresponding master medium in a disk 7 from the tape 6 by an inputted code number. A data group in the master medium stored in the disk 7 is transferred to copying machines (8-10) by the processing of the host computer 3. The machines (8-10) copy transferred data of the master medium on floppy disk media (11-13). In such a way, it is possible to prevent the mis-copying or the damage of the master medium at the time of insertion due to the taking out of the master medium or mis- insertion from being generated.</p> |
