Abstract

PURPOSE:To identify whether a copied recording medium can be used or not and to prevent important data from being lacked or damaged by controlling a copying order in a copying process. CONSTITUTION:A character processor is provided with a copy control means 130 for copying data stored in a data area 110A of one storing medium 110 to a data are 120A of the other storing medium 120, then copying data stored in a data management area 110B of one storing means 110 to a data management area 120B of the other storing medium 120. Since the data management part 120B of the recording medium 120 is incomplete when the copying is incomplete, processing using the recording medium 120 is invalidated. Consequently, an operator can be recognized, the use of the incomplete recording medium can be removed and the generation of data lack or the abnormality of processing can be preveiously prevented.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to an information storage system having an external storage device and having a copying function of copying the stored contents of one storage medium to another storage medium using the device. It relates to a processing device.

(Prior Art) Conventionally, the function of copying the stored content in the information processing device of this scale is simply a function for obtaining a copy, and the copying process, that is, the order of copying the content, etc., has not been taken into account. Ta.

[Problem that the invention seeks to solve]

Therefore, in conventional devices having such functions,
Assuming that the data management section located in the storage area of the copy source storage medium is copied first, if the copying process is canceled for some reason after copying in the data management section, the data management section will be copied. This means that the data section located there has been copied in an incomplete form. When using a copy destination storage medium that has been copied in this way, the data control unit exists normally, so it is considered to be a storage medium with normal memory contents, and the operator can process the data without being aware of the abnormality. I end up continuing.

This causes serious problems such as data loss or processing abnormalities.

[Means for solving problems]

The object of the present invention is to solve such problems and prevent the occurrence of abnormalities in storage media due to abnormalities in copying. In an information processing device including a device ioo and having a function of copying the storage contents of one storage medium 110 to another storage medium 120 using the device 100, one storage medium 11
The data stored in the data area 110A of the first storage medium 110 is copied to the data area 120A of another storage medium, and after copying, the data stored in the data management area 110B of the first storage medium 110 is copied to the data management area of the other storage medium 120. 120B.

(Function) According to the present invention, if the copying is incomplete, the data management unit 120B of the storage medium 120 is incomplete, so even if processing is attempted using the t0 medium 120, the data management unit 120B is incomplete. Processing is not allowed. This allows operator recognition, avoids the use of incomplete storage media, and prevents data loss and processing abnormalities in advance.

(Example) Hereinafter, the tree invention will be described in detail with reference to the drawings.

FIG. 2 is a block diagram showing one embodiment of the present invention.

In the figure, reference numeral 1 denotes a control device forming a main control unit, which includes a ROM that stores programs corresponding to the processing procedures described later in FIG. 4 for controlling each connected component, and a CPU that executes the procedures. , RAM for work, etc. 2
is an external storage device, and in this embodiment, a floppy disk device (FDD) is used. Reference numeral 3 denotes a storage medium applied to the external storage device, ie, FDD 2, and in this embodiment, it is a floppy disk (FD).

Reference numeral 4 designates a keyboard for issuing copy commands, and reference numeral 5 designates a display device for displaying and outputting messages such as the completion of copying.

In the above configuration, the copying process of the floppy disk 3 will be explained.

FIG. 3 is a diagram for explaining the contents of the floppy disk 3 and an outline of copying. Here, FDs is a floppy disk that stores the contents to be copied (hereinafter referred to as a source floppy disk), and FDs and FDt are floppy disks on which the contents to be copied are written (hereinafter referred to as a target floppy disk). The floppy disk 3 has tracks assigned sequential numbers starting from 0, and the internal position is determined by the track numbers. The contents consist of a data management section and a data section, and the data management section and the data section are respectively assigned to track numbers O to 4.
It is assumed that the data section is located at 5 to n. Further, the data management section holds data that centrally manages the data in the data section.

Next, the processing contents in this embodiment will be explained using FIGS. 4(8) to 4(C).

FIG. 4(8) shows two main processes of the copying process in this example, and FIG. 4(B) and (C) each show the two processes in detail.

For example, if an operator uses floppy disks FDs and
When t is set in the FDD 2 and a copy command is given from the keyboard 4, the data in the data management section of the target floppy disk FDt is erased in step St in FIG. This is to enable identification of incompletely copied floppy disks according to the purpose of the present invention, and details are shown in Figure CB).

That is, first, as an initial setting in step Sit, R
The contents of the track number counter provided in AM are set to the first position (ie O'') of the data management section, and then in step 512 the target floppy disk FDt is set.
Delete the data management section of the corresponding track number. Next, in step 513, it is determined whether the current track number is the end track number of the data management section (ie "4"), and if the determination is negative, the track number counter is incremented in step 514, and again in step s12. Execute. If it is the end track number, the process of step S1 is ended.

Next, in step s2 of FIG. 2A, the contents of the source floppy disk FDs are copied to the target floppy disk FDt from the data section, and then the data management section is copied. This is to copy the data management section erased in step Sl at the end of data copying.
The details are shown in Figure (C).

That is, in this embodiment, since the floppy disk has the contents shown in FIG. 3, the track number at the end of the data section (i.e. n) is set in the counter in the initial setting in step 521, and The contents of the track with the corresponding track number of the source floppy disk FDs are copied to the track of the target floppy disk FDt with the same track number. Next, in step S23, the end of copying is determined based on whether the content of the track number counter is O or not. If the determination is negative, the track number counter is decremented, and again in step S22.
Execute. If it is the end, the step S2 processing is ended, and the operator is notified by, for example, displaying a message to that effect on the display 5.

In this way, in this embodiment, the data management section of the target floppy disk FDt is erased in advance, data is written, and the data management section is written after the erasure is completed. If the process is stopped for some reason, the target floppy disk FDt will have no contents in the data management section, so even if you try to use it, it will be easy to identify the incompletely copied floppy disk. .

In this embodiment, a copying process using a floppy disk as a storage medium has been described, but the present invention is also extremely effective and applicable to information processing apparatuses using other external storage devices such as hard disks and RAM backs. Of course, it is easy to apply.

(Effects of the Invention) As described above, according to the present invention, by performing simple control that takes the copying order into consideration during the copying process, it is possible to identify whether or not a storage medium can be used after copying, and important data can be An excellent effect can be obtained in that chipping, destruction, etc. can be prevented.
