Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a composite image file system consisting of, for example, a microfilm file and an optical disk file,
In particular, it relates to backing up composite image file systems.

[Prior Art] Conventionally, a microfilm system has been used as a system for managing and utilizing an extremely large amount of non-code information (image information). Microfilm is superior in terms of economy, storage stability, resolution, etc., and has the advantage of being fast and capable of making large copies at high speed. suitable for

However, on the other hand, office automation has progressed rapidly in recent years, and there is a growing tendency for computers to be introduced into office equipment and for devices to be interconnected through communication circuits. In order to respond to such trends in computerization and communication, it is desirable that the information handled be stored in the form of electrical signals as much as possible. Therefore, electronic file systems have been attracting attention in recent years. Because electronic file systems store information in the form of electrical signals, they have features that microfilm systems do not have, such as high-speed retrieval and high-speed transmission. On the other hand, electronic file systems also diminish some of the advantages of traditional microfilm systems.

The disadvantages are that when inputting information, it is not possible to convert images in one shot through a lens system like in a microfilm system, and the human speed is slow because raster scanning is performed one by one. Copying cannot be done quickly and economically, there is no track record of sufficient long-term storage stability compared to microfilm, which has a long-term storage stability of 100 years, and microfilm has no legal evidence capacity. The reason for this is that it has not been done yet.

An even bigger problem is that when an electronic file system is introduced, the databases and information built up using conventional microfilm systems become unusable.

As already mentioned, both microfilm and electronic file systems have their advantages. In view of the recent trend toward office automation, electronic file systems have many advantages, but it is clear that microfilm systems cannot be ignored. Therefore, users are forced to choose between the two systems, or are forced to use two systems simultaneously, which is extremely inconvenient.

[Problems to be Solved by the Invention] Therefore, a composite image file system that combines a microfilm system and an optical disk file system is being developed. A file system that combines such different types of recording media is not just a combination, but an organic combination is desired. Furthermore, in an image file system that combines microfilm and optical disks, considering the amount of image files, it goes without saying that the amount of search information needed to search for those image files is enormous. A major challenge is how to ensure the integrity of this enormous amount of search information and make it easier to manage. The present invention has been made in view of the above points, and its purpose is to combine microfilm and one or more optical discs, to enable unified file management, and to maintain the integrity of the enormous amount of search information. The purpose of the present invention is to propose a composite image file system that secures the image data and facilitates its management.

[Means for Solving the Problems] For example, the structure of the composite image file system of the embodiment shown in FIG. It consists of a microfilm file 50 for reading and a workstation 10. The workstation 10 includes, for example, a hard disk (
The HD 2 stores search information for file searches, which has a common format for microfilm files and optical disc files, for each image. Furthermore, an area for backing up all of the search information (search information for both microfilm and optical disk image files) is secured on a predetermined optical disk.

[Operation] Under the above structure, the search information has a structure as shown in FIG. 4(b), for example, and this format is common between the microfilm and optical disk media. Generally, since the amount of image files is large, the amount of search information on the 1 (D2) is also large. By securing a copy of this large amount of search information in the backup storage area of the optical disk, it is possible to back up in case of emergency. Due to the security of having a backup and the security of having a backup, you can easily erase the search information on the HDZ temporarily.Also, due to the large capacity of optical disks,
It is possible to secure a backup of search information for image files on microfilm and optical disks, and once the backup is taken on the optical disk, it will not be erased, so the history of all image files can be traced. The predetermined optical disk may be an optical disk for recording image files, or a backup-only optical disk may be provided to ensure backup on the optical disk.

(HD2 memory map) FIG. 4(a) is a hard disk memory map.

It is. Its contents are a program area and a search information record storage area. FIG. 4(b) shows the format of the search information record stored in the HD2. As described above, the HD 2 stores the images stored in the optical disc file 40 as well as the search information corresponding to the image of each frame of the microfilm in the microfilm file 50 (see FIG. 5). It should be noted that the search information for different media of microfilm files 50 and 50 have a common format as shown in FIG. 4(b). By having a common format, management of search information on different recording media becomes efficient and easy. However, from the perspective of uniformly managing image files, it is not necessary to insist on having a common format; it is important to be able to distinguish between recording media.

As shown in Figure 0, which explains the format of the search information record in Figure 4(b), this format is divided into six fields. In the field 61, an identification mark (DEV-ID) indicating whether the image corresponding to this search information record exists in the optical disk file 40 or the microfilm file 50 is set. 1”, and the optical disc image “0”.
Define as 1. In the field 62, address information ADD on the medium on which the image corresponding to this search information record is recorded is set. In the case of an optical disc, this ADD contains the drive number, absolute address within the optical disc, etc., and in the case of a microfilm, the cartridge number and frame number of the microfilm file are stored.

In the field 63, the size of the image (PSIZ) corresponding to this search information record is set. This indicates, for example, whether the output image is A4/A3, etc. In the field 64, resolution information P-RES of the image corresponding to this search information record is set. In this example, the resolution is 400/300/2 at the time of input (registration).
Specify either 00dpi. In the field 65, various related information ODD such as compression ratio and positive/negative discrimination information regarding the image corresponding to this search information record is set as necessary. In the field 66, keyword information (KW) of the image file corresponding to this search information record is set. KW may be written in numbers, letters, or symbols.

When the operator stores a desired image in the optical disk file 40, these search information records are input using the KBD 6 of the workstation 10 in correspondence with this image, and are written to the HO2. In addition, if you have an outsourced company record a large amount of images on optical disks or microfilm, have the outsourced company write the search data to a floppy disk using a computer or the like in accordance with a predetermined format. The search data is transferred and stored from the FPD 3 to the HO2.

<Relationship of search information between each storage medium> The search information record for each image stored in the optical disk file 40 and the microfilm file 50 is the fifth one.
As shown in the figure, "M" indicates a microfilm and "OD" indicates an optical disk file. FIG. 5 illustrates a method for backing up search information records on HCl. That is, the backup of the search information record of the microfilm is stored in the FPD 3, and the backup of the search information record of the optical disk file 40 is stored in the optical disk drive. In addition to the individual backup method for each recording medium shown in FIG. 5, an embodiment of a backup method for backing up all search information records on HCl to a backup-only optical disk will also be disclosed (see FIG. 17 onwards). (Explained in ).

Below, the order of explanation of the embodiments is as follows: First, the l531 or MS51
An explanation of the operation for registering an image from a microfilm, an explanation of the operation for registration accompanying the medium conversion from a microfilm to an optical disk, and an explanation of the operation for starting or restoring based on the backup method shown in Fig. 5. Next, we will explain the backup method and operation for recovery in a system equipped with a backup-only optical disk.

<Data Structure of Optical Disk> Now, the relationship between the search information media is as shown in FIG. 5, and the relationship between the image file and the search information record in the optical disk file 40 is as shown in FIG. In FIG. 6, the optical disk file 40 stores four image files (their keywords 66 are "parts", "parts name", "parts", and "parts catalog"). The ADD fields 62 are "I FFFF", "I EFFF", and "IDFFF", respectively.
, "ICFFF". Here, the ADD 62 is 5 digits for convenience, and the MSD is the drive number of the optical disc file 40. That is, in the example of FIG. 6, the drive number is "1". In FIG. 6, the addresses of the optical disk file 40 are the highest addresses from the top to the bottom of the paper. Normally, low addresses have high credibility. Important data such as search information records are stored. In the figure, there are two image files with the same keyword name ("parts"), but this is because the image file with the address "I FFFF'" has been processed, for example, as a new image file with the same keyword 66. The optical disc of this embodiment is a so-called write-once type, and since old files cannot be erased, image files with the same keywords are allowed to exist, and the fact that these new and old files are mixed is the reason for its large capacity. This is one of the advantages of optical discs. In other words, the history can be traced from the search information record. Searching for image files on an optical disc is usually done by
A method is used in which all the search information records in the ID2 or the optical disk are read, and the read search information records are sequentially displayed on the CBr4 and left to the operator's selection of search information records.

(Registration of image from IS31) Fig. 7 is a diagram explaining the concept of the operation in which a document image is read by l531 and stored and registered in optical disk file 40.According to Fig. 7, the document read from l531 is The keyword 66, which is temporarily stored in the control unit 1 (I MEMll) and entered by the operator via the KBD6 without visually recognizing the CBr4, is registered in the ID2 and the image is stored in the optical disk file 40.At this time, the image is stored in the optical disk file 40. A backup of the search information is taken on the optical disk file 40.

The above is an outline of the image file registration from 1531. Next, the registration control procedure will be explained according to the flowchart of FIG. In the flowchart of FIG. 8, examples of CBr4 screens are illustrated at steps as necessary.

After setting the image original to be registered on the optical disc in l531, the registration volume is specified in step S2. This registered volume is the ID (name) of the optical disc, etc. Next, in step S4, according to the instructions displayed on the CBr4, select the image reading mode (image file attributes), for example, the resolution (=200dpi/300dpt/400dp
i) Specify the document size (A3.A4.B3.B4) using the PD5 via the menu screen. In step S6, the image is 1531 according to the specified attribute.
is read from and temporarily stored in IMEMII in wsto. The data stored in IMEMII is converted for display by the BMU 16 in step S8, and then
VRAM1. in CRTIF15. : Stored and displayed on CBr4. The operator visually checks the displayed image to confirm whether it has been loaded correctly. If the image has been read correctly, the image just read is 1 in step S12.
Determine whether the page is a page or the first page of a multi-page page. This can be easily determined from the operator's instructions or the attribute designation made in step s4. The reason for making such a determination is to set the keyword 66 on the first page. Now, if it is determined in step 512 that the page is one page or the first page of multiple pages, a keyword 66 is set in step S14, and the manually entered keyword 66 is temporarily stored in the DMEM 20. As mentioned above, the keyword 66 is input through the PO2 or KBD6 while viewing the CRT4. After being stored in the DMEM 20, the keyword 66 is converted into the format shown in FIG. 4(b) along with other information, and a search information record is written to the HD 2 in step S16, and the process proceeds to step S18. If the determination in step S12 is NO immediately in step S12.
Proceed to step 318 from HD2 of the search information record.
When the storage, etc. in IMEM
The image information temporarily stored in II is written to the optical disc via ICU 18 and 0DIF 12.

Repeat the above operation until all pages are completed (step 520)
, when all pages are completed, the search information record of the image original is written to the optical disc file 40 as a backup in step S22. At this point, as shown in FIG. 6, a search information record for image file registration and backup has been stored in the optical disk file 40. If so,
Even if the search information record of the image information is destroyed due to some trouble in the HD 2, the same search information record exists on the optical disc file 40, so it can be easily restored.

Other information added to the keyword 66 in the search information record includes information on whether the image information is an optical disc or microfilm, address information on where on the optical disc it is stored, and A4. Size information such as A3, resolution information, compression in the ICU 18, etc., that is, the amount of information stored on the optical disk and whether it is negative information or positive information, etc., are determined by wsto based on information in the conversation with the operator and information from the optical disk. Added to the beginning of the search information record.

(Registration from an optical disc) What was described above was registration from l531, but as mentioned above, it is conceivable that a trader registers from an optical disc on which an image has already been written.In this case, the keyword 66 is In some cases, images may be written to an FPD, etc., in the same way as images are written to the FPD.In this case, in step S6 of FIG.
Load the search information from the PD3, and each time you read it, set the keyword 66 and update the search information from the HD.
2 and backup to an optical disk.

<Registration of microfilm file> Registration of microfilm usually means reading the microfilm image that has already been made into film from the MS51.
A search information record including a cartridge number, frame number, etc. is created and registered on the HD 2. The outline of the operation is shown in FIG. 9.The feature of this embodiment is that the search information record is registered on the HDZ, and a backup search information record is also stored on the FPD 3.

FIG. 10 is a flowchart showing the control procedure for microfilm registration. When operating a microfilm file, an operator first sets each cartridge in the loading section 54 as shown in FIG. . Unlike optical discs, when registering a microfilm file, the frame number on the microfilm is used as an absolute address. Therefore, the cartridge number, frame number, etc. are input to the ADD 62 added to the search information record, which becomes the search information record. Furthermore, since the microfilm files are similar files, the area of the HD 2 can be reduced by providing one search information record for a plurality of consecutive frames of microfilm that should have the same keyword 66.

The control procedure when the MA 52 is not used will be explained according to FIG. First, a microfilm cartridge containing image information for which the keyword 66 should be registered is set in the loading section 54, and the image reading mode (image attributes) is instructed in step S30, similar to the image scanner (IS) input described above. do. Reading is started in step S32, and the read image information of one frame is temporarily stored in IMEMII, and displayed on the CRT 4 in step S33. Check whether the reading was normal in the same way as when registering from l531 (step 534), step S
At step 36, it is determined whether the image file is one frame or continuous frames. In step S40, the operator issues a keyword 66 instruction, and in step S42, the search information record is stored in the HD 2. In step S44, a backup of the search information record is taken on the FPD 3.
゛For the first image information, the operator specifies the frame number of the microfilm, and if registering sequentially, proceed to step S3.
If it is set to 0, the WSIO increments the ADD field 62 by +1 to advance the microfilm by one frame, and to record the search information of the input image intermittently, specify the frame number each time. Once registered on the HD 2, all search information records are managed on the HD 2, similar to the optical disc described above.

<Registration of composite image> Next, according to FIGS. 11(a) to (d), the image read from the microfilm and the image read from the optical disk file are combined, and the combined image is registered and the search information record is backed up. I will explain about it.

In step Sho in the previous fmtt diagram (a), an image is input from the microfilm. Next, in step S52, an image is input from the optical disc file 40.
50 and step S52 are subroutines whose details are shown in FIGS. 11 (d)) is executed.

The search subroutine searches the HD 2 for a search information record having the specified keyword 66 (step 5).
80). The searched search information code is stored in the DMEM 20 (step 582), and in step S84 it is determined whether the image is in the microfilm file 50 or the optical disk file 40 based on the value of DEVID 61 in the search information record.

If the value of the identification mark DEV-ID61 is 1'', it is assumed that the image is recorded in the microfilm file 50, and a search is performed for the corresponding image frame in the microfilm file 50 according to the address information ADD62 of the search data. (Step 58B), and the image of the retrieved microfilm frame is read (Step 388).
: Then, the optical disk file 40 is searched according to the address information ADD (step 590), and the image file is read (step 592).

The image information read from the microfilm file 50 or the optical disk file 40 is sent to the workstation 1.
One page is stored in IMEMII 0 (step 594
), this ends the search subroutine.

Returning to step S54 of ml1 figure (a), ■MEMI
Process the two images in I. This processing is BMt
This is done by J16. If this processed image needs to be registered, the process advances to step S60, and a keyword 66 is set in order to create a new search information record. The processed image is stored in the optical disk file 40 in step S62, a new search information record is stored in HO2 in step S64, and a backup of the search information record is stored in the optical disk file 40 in step S66. To put the operations shown in FIGS. 11(a) to 11(d) in accordance with FIG. 6, for example, the image file "component" from the microfilm and the image file "component name" from the optical disk file 40 are synthesized. Thus, a new image file "parts catalog" is created on the optical disk file 40 (FIG. 12).

Incidentally, in the above explanation, the combination of images on a microfilm and an optical disc was explained, but it is also possible to transfer an image from a microfilm to an optical disc in the same way.

<Backup File Loading> Backup file loading is, for example, when the search data on the HO2 is destroyed due to a failure or the like, or during the initial processing of the JOB program in the embodiment described later, the backup file loading is performed from the optical disk file 40 and FPD 3 as shown in FIG. As <H
This refers to the operation of reconfiguring search information records on the DZ.

FIG. 13 shows the concept of its operation, and FIG. 14 is a flowchart of its control procedure.

According to FIG. 14, first, in step 5100, the optical disk and FPD 3 to be restored are set in the drive. In step 5102, all search information records of the set optical disc are read and stored on the HDZ. This operation is performed for all optical disks that require restoration. Next, in step 5106, the search information record of the microfilm file 50 is similarly restored from the FPD 3. In this way, search information records can be restored extremely easily.

<Deleting and restoring search information records> The above control procedure shows how to restore all search information records, but it is extremely difficult to specify a specific keyword 66 and restore only the search information records that have that keyword 66. It's easy. An example of this is deletion of a portion of a search information record and restoration of the deleted search information record from a backup. FIG. 15 shows an example of deletion. Needless to say, deletion in this case refers to deletion of only the search information record on the HDZ. Figure 16 (a
) and (b) show flowcharts of control procedures for deletion and restoration of search information records, respectively. To give an overview of the search information records to be deleted, first set a keyword 66 on the CRTJ, display the search information records in the HDZ with that keyword 66 on the CRT 4, and then the operator selects the desired search information record. Delete (16th
Figure (a)). Similarly, the search information record obtained from the keyword 66 is searched and restored in the optical disk file 40 or FPDB by setting the keyword 66 to restore the deleted search information record (see FIG. 16).
b)).

In this way, the format of the search information records for the optical disk file 40 and the microfilm file 50 is made common, and the search information records for both files are mixed and stored in the common HD 2, so that image search is possible. The operator who performs this search can search for keywords corresponding to the image to be searched without considering the file to be searched for.
By inputting 6, the desired image information can be obtained.

That is, since the file (medium) in which the image is actually recorded and the address within that file are managed in the search information record, the operator does not have to be aware of the composite medium when searching for an image. This makes it easier to search for images centrally.

You can also back up your search information on an optical disk or FPD3.
Since the search information is prepared for, it is easy to restore the search information, and management is ensured by distinguishing the backup media.

Furthermore, by having a backup, you can safely delete information that is infrequently used or search information that is outdated, so you can secure free space on your hard disk and search for keywords for new image information. can be registered.

(Composite image file system with a backup-only optical disk) In the image file system explained above, the backup of the microfilm search information record is on the FPD3.
The backup of the search information record of the optical disk file 40 was stored in the optical disk. In the composite file system described below, the above-mentioned search information records (including search information records for both optical disks and microfilms) are stored in an optical disk exclusively for backup. The advantages of providing such an optical disk exclusively for backup are as follows. Of course, it goes without saying that image files can also be stored on this backup-only optical disk.

As the scale of the composite file system increases, the number of optical disks and microfilms naturally increases.

In such cases, use optical discs.

and microfilm are divided by job (JOB).
OBS optical discs and microfilm are often used. Furthermore, if there are daily or monthly jobs for the same job, it may be desirable to perform the jobs with the latest date and time or monthly file configuration.

Furthermore, there are cases where it is desired to restart a JOB on a specific date. This takes advantage of the characteristic of optical discs that image files are stored one after another without being updated.

In such a case, if the search information records for each job or date and time (monthly) are backed up on a backup-only optical disk, the operator will be able to keep track of which optical disks and microfilms are required for each job. The search information on the backup-only optical disk can be read and processed. Furthermore, if the program of the JOB is also stored on a backup optical disk, only the initial start program needs to be stored in HO2, and it is easy to start the JOB at the desired time.
You can restart OB.

Further, in a normal image file system, as described above, it is essential to register keywords of image files. Since this registration work is a large amount, usually once registration is made on the HDZ, various JOB programs share and use the search information on the HO2.

Since these files are shared, it becomes difficult to manage files for each JOB program and each date as described above.

Further, these search information are not stored in an equivalent system, but are simply stored in the order of registration.

<Outline of JOB program> An optical disk exclusively for backup is proposed based on the above requirements. Therefore, the JOB program of the composite image file system proposed in this embodiment has an outline as shown in FIG. That is, as shown in FIG. 24, it is assumed that backup files of search information for microfilm and optical disk rfM & files have already been created in each of the FPD 3 and the optical disk backup area for image files according to the method of the above-described embodiment. . First, the JOB program saves these backup files to the JOB.
Copy it onto HO2 as search information used by the program. When the JOB program ends, all the search information on HO2 is copied again to the backup-only optical disk. The backup file copied to the backup-only optical disk is stored as search information belonging to that JOB program. Such backup files for each JOB program are stored one after another on a backup-only optical disk each time a different JOB program is run. Since optical disks have a large capacity, they can withstand storing such backup files. When running the same JOB program, search information with the name of the JOB program is called from the backup-only optical disk onto the HO2, and image files are searched and reprocessed according to the search information.

Here, if we explain according to the flowchart in Fig. 23,
In step 5170) the search information storage area on the tDZ is cleared. In step 5172, it is determined whether the JOB program is an initial start. If it is an initial start, the process of loading the backup file described above (FIG. 14) is executed in step 5174. In step 5100 of this backup file load, the relevant JO
All you have to do is load the floppy disk and optical disk necessary for B into the drive. By loading this backup file, search information in units of JOB programs is reconfigured on HO2. Based on this search information, the relevant business IA process is performed in step 5178, and step S! 80, the latest search information that is expanded on the HO2 is copied (Fig. 20) to the backup-only optical disk (details of this flow will be described later). Therefore, when restarting the JOB program, If the answer is NO in step 5172, a warm restart (FIG. 22) is executed in step 3176. As will be described later, this warm restart reconstructs the search information on the HDZ from the backup file on the backup-only optical disk.

<Configuration of backup-only optical disk> Figure 17 (a)
-(e) show examples of record formats written on this backup-only optical disc. Figure 17 (a
) is 7 in Figure 0, which shows the format common to each record.
0 is the record type. Record type 70 is “0”
There are four types: ” to “3'. Records of each type are shown in FIGS. 17(b) to (6). FIG. 17(b) is a disk type record. Record type 70 of the disc type record is “0”, disc type 71
When it is "O'", it means that the optical disc is a backup-only optical disc, and when it is "1", it means the above-mentioned normal optical disc.

FIG. 17(C) is a JOB record. The record type 0 for the JOB record is "1". Field 72 contains the JOB name, and field 73 contains the JO name.
The date on which the B record was written to the backup-only optical disk is stored in the field 74, and the volume name of the optical disk or the like used for the job is stored in the field 74. Figure 17(d)
is a search information record. The record type is “2”
". The search information shown in FIG. 4(b) is stored in the field 75. FIG. 17(e) shows a program record. Its record type 70 is "3".

If a program is paged or segmented, it can be stored in a backup-only optical disc with a predetermined record length.

FIG. 18 shows an example of the arrangement of the records shown in FIGS. 17(a) to (e) in a backup-only optical disc. A disc type record 80 indicates that this optical disc is a backup-only optical disc, and a JOB The search information record 82 following the record 81 and subsequent records contain all the search information for the optical disk file or microfilm used in the JOB. JOB program 83 has the relevant J
The OB program is stored. JOB record 84 indicates that another JOB record and search information record newly follow.

Storage of backup files on a backup-only optical disk) Storage of backup files on a backup-only optical disk is performed taking priority into consideration.

FIG. 19(a) shows the number of each drive of the optical disks connected to this composite image file system. The total number of optical disks connected to the combined file system is, for example, eight at most. FIG. 19(b) shows flags in the DMEM 20, and each flag indicates whether or not the corresponding optical disk drive is currently being used.

FIG. 20 is a flowchart illustrating the order of determining which drive should be loaded with a backup-only optical disk under the optical disk configuration of FIG. 19. The reason why such flowchart control is necessary is to take into account the operator's usability when a large number of optical disk drives are connected as shown in FIG. 19. That is, WSIO
independently determines the drive in which the backup-only optical disk should be loaded in the most convenient position from the operator's point of view,
The drive number is displayed on the CRTJ to prompt the operator to load the backup optical disk.

First, in step 5110, it is checked whether all drives are empty.

If all the drives are empty, a message is displayed on the CRT 4 in step 5112 saying, ``Load a backup-only optical disk into drive No. 0''. “0”
The numbered drive is chosen because it is closest to the operator.

If the backup-only optical disk is loaded into the drive numbered "0," a subroutine for saving to the backup-only optical disk is executed in step 3126. If any optical disk is in use in step 5110, it is checked in step 3116 whether all optical disk drives are in use. If all the drives are in use, for the same reason, a message "Replace drive number 0" will be displayed on the CRTJ in order to load the backup optical disk into drive number O. . In step 5116, if any drive is free, identify the drive closest to the operator (the drive with the lowest number), and
Load a backup-only optical disk into the drive.'' is displayed on the CRT4. All of the above judgments are made with reference to the flags in FIG. 19(b).

FIG. 21 shows details of step 5126 of FIG. 20, which is the save subroutine. First, in step 5128, it is determined whether the loaded optical disc is a backup-only optical disc. This is a disk type record (first
This can be seen by examining Figure 7 (b)). A JOB record (FIG. 17(C)) is set in steps 5130 to 5134, and the JOB record is written to the backup-only optical disk in step 5136. Next, step 31
38. This differs from the embodiment shown in FIG. 5 in that in step 5140, a search information record (FIG. 17(d)) and a program record (FIG. 17(e)) are written, and a microfilm search information record is also written. As mentioned above, there are.

<Warm restart> Warm restart reads the JOB record, search information record, etc. from the backup optical disk.
The job is expanded on the HDZ and the job is restarted. This restart is suitable for a system that uses different optical discs or microfilms for each job. The operator of that JOB can call up all search information from the backup-only optical disk using the JOB record corresponding to the JOB. Since this search information is backed up, there is no need to re-register the search information for each job, and the image file system can be easily used. It is also effective when the data on )(D2 is unreliable).

FIG. 22 shows a flowchart of the warm restart control procedure. When this control program is stored in HD2, it is called from HD2 to PMEM9, but
The information is stored in advance in a ROM (not shown), etc., in consideration of cases where the reliability of the information may be unreliable. First, in step 5150, the drive number of the optical disk in which the backup-only optical disk is loaded is specified from the CRT 4. After confirming that the optical disc loaded in the drive is a backup-only optical disc (step 5151), in step 5152, the user enters the 508 name and date for restarting. In step 5154, the backup-only optical disk is searched for the JOB record corresponding to the 508 people manually entered, and if found, in step 5156, the search information record following the JOB record is read out and developed on the HDZ. If necessary, the program is also read out and expanded on the HDZ in step 5158. In this way, the search information record can be very easily restored with a desired system configuration that matches the JOB. The operator displays the volume name in the JOB record on the CRT4 and selects the job.
Since you can know what kind of optical discs and microfilms are needed for the purpose, you can prepare the optical discs or microfilms according to the instructions.

Effects of the embodiment having a backup-only optical disk> As explained above, by using an image file system having a backup-only optical disk, (1) all search information and even programs can be stored.

(2) Since the file structure of the image file system can be reconstructed from a copy of the search information managed in the JOB record in the backup-only optical disk, it is possible to manage the JOB=file for each job and for each date. That is, JOB
It becomes possible to systematize program-oriented file management.

(The following is a blank space) [Effects of the Invention] As explained above, according to the present invention, a composite image file system in which a microfilm and one or more optical disks are organically combined can be proposed, and furthermore, it is possible to fully search all image files. By backing up information on an optical disk, the integrity of search information is ensured and its management becomes easy. Furthermore, if you provide a backup-only optical disk and take backups on that backup-only optical disk,
Search information management becomes easier.
