Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage medium copy method, and more particularly to a storage medium copy (duplication) method in a document management file system using a storage medium such as an optical disk.

2. Description of the Related Art In recent years, a document image file system using a large-capacity storage medium such as an optical disc has been developed as a storage management method for a large number of documents, and 15,000 documents can be registered on one optical disc. In general, when image information is stored on an optical disc, the image information is additionally recorded in a variable length for each document and the management information for each document is stored in a fixed length.

Conventionally, as a method of copying this kind of optical disc,
The image information is read according to the management information of the original optical disc and written in the new optical disc for each document, and the management information including the new address of the image information written in the new optical disc is written for each document.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, if an optical disc is a write-once, large-capacity, and unreadable document due to the presence of a defective sector, a document image that cannot be copied is generated, and a document of management information of the new optical disc is generated. The number is a missing number, and there is a problem that a compatible optical disc copy cannot be realized.

It should be noted that when a document image that cannot be copied is generated, it can be managed using a conversion table, but even in this case, the optical disc itself is not compatible and this is not a complete solution.

In addition, when a document image that cannot be copied occurs, the copy operation is interrupted, and the document numbers can be made consecutive by separately reading the individual defective documents and copying them. However, in this case, the optical disc is large. Due to the capacity, it is impractical to interrupt the copy operation.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a method capable of copying compatible storage media having consecutive document numbers, and efficiently copying.

Means for Solving the Problems In order to solve the above problems, the present invention provides an area in which management information is stored in advance in a second storage medium in which image information in a first storage medium is stored, and a storage area. It is characterized in that an area in which the management information is stored by subsequent input when the generated image information is not normal is formed separately.

With the above-described configuration, the present invention stores the image information of the first storage medium in the second storage medium for each document, determines whether the stored image information is normal, and if it is normal, The management information is stored in the management information storage area of the second storage medium. On the other hand, if the management information is not normal, at least the document number is stored in the management information storage area, and a rear input area is secured to store the address and the like. Therefore, the copying operation can be performed efficiently without interruption.

Further, since the abnormal image information is additionally recorded after correction and stored, and the address and the like of the image information is stored in the post-input area, the document number does not become a missing number, and a copy of a compatible storage medium can be performed. It becomes feasible.

Embodiments Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a document image file system having an optical disc copy function according to an embodiment of the present invention.

This system has two optical disc devices 1 and 2, and the optical disc device 1 reads a document of an original optical disc (standard optical disc) in which image information and its management information are stored,
The optical disc 2 is used for writing the document of the standard optical disc into a new optical disc (editing optical disc).

This system is also input by the file controller 3, a keyboard 4 for setting various modes such as a registration mode, a read mode, and a copy mode, and for designating a document number at the time of reading. Display 5 for displaying data and read images
And a scanner 6 for reading an original image, a printer 7 for outputting image information, and the like.

The file controller 3 includes interfaces with the optical disk devices 1 and 2, the keyboard 4, the scanner 6 and the printer 7, a display controller of the display 5, an image memory for temporarily storing image information, a central controller (CP).
U) and a memory storing an execution program of the CPU as shown in FIG.

FIG. 2 shows the optical disk 8 according to the present invention, and FIG. 3 shows the storage format of the optical disk 8. As shown in FIG. 2, the optical disk 8 has n storage tracks T _{1 to} T _n formed in the circumferential direction divided into ₃₂ sectors S _{1 to} S ₃₂ in the radial direction. As shown in FIG.
A fixed-length document management information area 8a, and a post-input area 8b in which, when a defective document occurs during copying, the address and the like of the corrected document are stored later,
It is divided into an image area 8c in which variable length image information is stored. The management information of one document includes the number of the document, address information, and other search information.

FIG. 4 shows the relationship between the management information, the post-input data and the document image information stored in the area shown in FIG. 3, and the document image information of each document number has a different number of pages. Therefore, compatible optical disks cannot be copied unless the management information is stored in the order of the document numbers when additionally recording the document image.

The operation of the CPU of the file controller will be described below with reference to FIG.

First, when the copy mode is set via the keyboard 4 in step (hereinafter referred to as ST) 1, the first document of the reference optical disk, that is, the document number 1 is designated, and the subsequent ST
Read the document encryption management information specified in 2.

In ST3, the image information for one page is read by the address information of the read management information and written in the image area 8c of the editing optical disk. In ST3 to ST5, the image information of one document is read from the standard optical disc and recorded on the editing optical disc.

When the copying of the image information of one document is completed, the process proceeds from ST5 to ST6, and it is determined whether the copying is normal or not. If the copying is normal, the process proceeds to ST7, and new management information including address information of the editing optical disc with newly written image information is written in the management information area 8a of the document number of the editing optical disc.

On the other hand, if the copy is not normal in ST6, the process branches to ST8, and at least the document number of the management information is written in the management information area 8a, and the post-input area 8b is confirmed and the address information is written. Similarly for ST2 to ST10
At, the image information of the rest of the document is written.

That is, this operation does not interrupt the operation of the apparatus because image information or the like is written regardless of whether the copy is normal or defective.

Next, the processing of the image information which is determined to be defective will be described. First, the operator operates the keyboard 4 to display the new management information of the edit optical disk on the display 5. In this case, it can be confirmed that the image information of the document number having a display indicating that the rear input area 8b is secured is a defective copy.

Image information is read from the standard optical disk and the edit optical disk for this defective document and displayed, the standard optical disk is corrected (for example, dust is removed), and this image information is recorded again on the edit optical disk. In this case, new address information is obtained and stored in the input area after being secured.

Therefore, since the document number of the standard optical disk and that of the editing optical disk match, a compatible optical disk copy is realized.

In the above-mentioned embodiment, the copying of the optical disk has been described, but the present invention can be applied to a storage medium of a document file which handles other images.

As described above, according to the present invention, when the document image of the first storage medium is being copied, the document number is valid even if a defective document image occurs, and the second storage medium stores the document number. Since the fact that there is an input area after the new management information is recorded, the device can efficiently copy without interrupting the copy operation, and the defective document image can be copied after the copy operation is completed. Since the post-correction postscript is added and the address information and the like is recorded using the post-input area, the document number does not become a missing number and a compatible copy can be realized.
