Description

Description: TECHNICAL FIELD The present invention relates to a composite image file system including, for example, a microfilm file and an optical disk file,
In particular, it relates to backup of a composite image file system.

[Prior Art] Conventionally, a microfilm system has been used as a system for managing and utilizing an extremely large amount of non-coded information (image information). Microfilm has advantages such as economical efficiency, storability, and resolution, and has the advantage of being able to input a large amount of data at a high speed and to store and manage the file information, which is increasing year by year. Are suitable.

However, on the other hand, in recent years, office automation has been rapidly developed, and there is an increasing tendency for computers to be introduced into office equipment and for each equipment to be connected to each other through communication circuits. In order to cope with the tendency toward computerization and communication, it is desirable that the information to be handled be stored in the form of electric signals as much as possible. Therefore, the electronic file system has been attracting attention in recent years. Since the electronic file system stores information in the form of electric signals, it has features such as high-speed retrieval and high-speed transmission that are not found in microfilm systems. On the other hand, the electronic file system impairs the advantages of the conventional microfilm system.

The disadvantage is that when inputting information, it is not possible to convert the image in a one-shot manner through a lens system like a microfilm system, and the input speed becomes slower because the raster scan is performed one by one, and copying of several hundreds or less copies Is not possible at high speed and economically, there is no record of sufficient long-term storage stability compared to microfilm with long-term storage stability of 100 years, and the legal evidence capability recognized by microfilm is recognized. That is not the case. A further big problem is that when the electronic file system is introduced, the database and information built up using the conventional microfilm system cannot be used.

As already mentioned, both the microfilm system and the electronic file system have their respective advantages. In view of the trend toward office automation in recent years, it is clear that the electronic film system has many advantageous aspects, but the microfilm system cannot be ignored. This either forces the user to choose between the two systems, or suffers the great inconvenience of having to use the two systems in parallel at the same time.

[Problems to be Solved by the Invention] Therefore, a composite image file system combining a microfilm system and an optical disc file system is being developed. Such a file system in which different kinds of recording media are combined is not a simple combination, but an organic combination is desired. Further, in an image file system in which a microfilm and one or a plurality of optical disks are combined, it is natural that the search information for searching those image files becomes enormous in view of the amount of image files. A major issue is to ensure the maintainability of this enormous amount of search information and facilitate management.

The present invention has been made in view of the above points, and an object thereof is a composite image file system in which file recording devices of different recording forms such as a microfilm and an optical disc are combined, and these recording are unified. An object of the present invention is to provide a copy image file system capable of managing the files of the apparatus, surely preserving the search information that tends to become huge, and easily managing the same.

[Means for Solving the Problems] In order to achieve the above object, the composite image file system of the present invention is different from the first recording means for recording an image file, and the recording mode of the first recording means. Second recording means for recording an image file in a recording form; keyword information indicating an arbitrary image file of the first recording means and the second recording means; and the image file being the first recording means or Storage means for storing search information including identification information indicating in which of the second recording means the information is stored, and position information indicating a storage position of the image file in a format corresponding to the identification information; Input means for inputting keyword information in order to search for the target image file in the first recording means and the second recording means; and the input keyword information and the storage means. Reading means for reading the target image file based on the identification information and the position information indicating the storage position of the image in a format corresponding to the identification information, which is determined by the keyword information included in the stored search information. A storage for storing, in the first recording means, search information in which the identification information included in the search information represents the first recording means among the search information stored in the storage means in a mixed manner without any distinction of the identification information. Control means is provided.

[Operation] In the above system, the search information used on the device side for searching the image file is the keyword information for searching the image file, and either the first recording means or the second recording means. Storage information and position information indicating the storage position of the image in a format corresponding to the identification information.

Further, when the user inputs a keyword of the image file to be searched, the reading means determines the identification information and the identification information, which is determined by the input keyword information and the keyword information included in the search information stored in the storage means. The target image file is read out based on the position information indicating the storage position of the image in a format corresponding to the identification information.

Therefore, the user can take out the target image file simply by inputting the keyword information indicating the target image file without worrying about which recording means stores the target image file. It will be possible.

Further, although the search information is stored in the storage means in a mixed manner without discriminating the identification information, even if the storage means fails, the first recording means stores the identification information included in the search information in the first information. Since the search information representing the first recording unit is stored, the search for the image file in the first recording unit is quickly backed up. That is, it is possible to surely maintain the huge amount of search information that is likely to be lost.

[Embodiment] As a preferred embodiment of the present invention for achieving the above object, for example, the structure of the composite image file system shown in FIG. 1 is an optical disk file having an image reading and writing function.

<HD2 memory map> Figure 4 (a) shows a hard disk memory map. Is.
The 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 HD2. As described above, the image stored in the optical disk file 40 and the search information corresponding to the image of each frame of the microfilm of the microfilm file 50 are also stored in the HD2 (see FIG. 5). It should be noted that the search information for the different media of the optical disk file 40 and the microfilm file 50 has the common format shown in FIG. 4 (b).
By having a common format, management of search information in different recording media becomes efficient and easy. However, from the viewpoint of managing the image files in a unified manner, it is not necessary to stick to having a common format, and it is essential that the recording media be distinguished.

The format of the search information record shown in FIG. 4 (b) will be described. As shown in the figure, this format is divided into 6 fields. The field 61 is set with an identification mark (DEV-ID) indicating whether the image corresponding to the search information record is present in the optical disc file 40 or the microfilm file 50. In this embodiment, the microfilm image is defined as "1" and the optical disc image is defined as "0".
In the field 62, address information ADD on the medium on which the image corresponding to this search information record is recorded is set. If the optical disk is an optical disk, this ADD includes the drive number, absolute address in the optical disk, etc. In the case of a micro film, the cartridge number and frame number of the micro film are stored.

In the field 63, the size of the image (P-SIZ) corresponding to this search information record is set. This indicates, for example, that the output image is A4 / A3 or the like. In the field 64, resolution information P-RES of the image corresponding to this search information record is set. In this embodiment, one of 400/300/200 dpi is designated as the resolution when inputting (registering). The field 65 is set with various related information ODD other than the compression rate and the positive / negative discrimination information regarding the image corresponding to the search information record, if necessary. The keyword information (KW) of the image file corresponding to this search information record is set in the field 66. KW is a number,
It may be written in either letters or symbols.

When the operator stores a desired image in the optical disc file 40, these search information records are input using the KBD6 of the workstation 10 corresponding to this image and written in the HD2. In addition, when the subcontractor records a large number of images on the optical disk or the microfilm, the subcontractor writes the search data on the floppy disk using a personal computer or the like according to a predetermined format. This Floppy disk search data is transcribed and stored in HD2 from FPD3.

<Relationship of search information between storage media> Optical disk file 40 and micro film file 50
As shown in FIG. 5, the search information records for the respective images stored therein are mixedly stored in HD2 according to the format shown in FIG. 4 (b). In the figure, "M" indicates a micro film and "OD" indicates an optical disk file. FIG. 5 illustrates a method of backing up search information records on HD2. That is, the backup copy of the search information record of the micro film is stored in the FPD 3 and the backup copy of the search information record of the optical disk file 40 is stored in the optical disk drive. In addition to the individual back-up method for each recording medium shown in FIG.
An example of a backup method for backing up all the search information records above in a backup optical disk is also disclosed (explained in FIG. 17 and subsequent figures).

The order of the description of the embodiments is as follows. First, the operation description for the registration of the image from IS31 or MS51, the operation description for the registration accompanying the medium conversion from the microfilm to the optical disk, and then the backup pattern in FIG. The operation description for restart or recovery based on the method, and then the backup method and the operation description for the recovery and recovery in the system provided with the optical disk dedicated to the backup are given in order.

<Data Structure of Optical Disk> The relationship between the search information mediums is as shown in FIG. 5, but 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 (the keywords 66 are “part”, “part name”, “part”, and “part catalog”) as an example. The ADD fields 62 of those image files are "1FFFF" and "1E", respectively.
FFF "," 1DFFF "," 1CFFF ". Here, ADD62 has a 5-digit number for convenience, and its MSD is the drive number of the optical disk file 40. That is, the drive number is" 1 "in the example of FIG. In Fig. 6, the address of the optical disk file 40 is a high address from the top to the bottom of the page. Usually, a low address has high reliability, so important data such as a search information record is stored. Although there are two image files with the same keyword name (“parts”) in the figure, this is because the image file with the address “1FFFF” has undergone image processing, for example, and is registered as a new image file with the same keyword 66. The optical disk of the present embodiment is a so-called write-once type, and since the old file cannot be erased, image files having the same keyword are allowed to exist, and the new and old files are mixed. The existence of the optical disk is consistent with its large capacity, which means that the history can be traced from the search information record.The search of the image file in the optical disk is usually performed in the HD2 or the optical disk. A method is adopted in which all the search information records are read and the read search information records are sequentially displayed on the CRT 4 and the operator is allowed to select the search information records.

<Registration of images from IS31> Figure 7 shows an optical disc file in which a document image has been read by IS31.
FIG. 8 is a diagram illustrating the concept of operations stored and registered in 40. According to FIG. 7, the document read from the IS31 is stored in the temporary control unit 1 (IMEM11), and while the operator visually recognizes the CRT4, the keyword 66 input via the KBD6 is registered in the HD2 and the image is recorded on the optical disc. Store in file 40.
At this time, a backup of the search information in the HD2 is captured on the optical disk file 40.

The above is the outline of the image file registration from the IS31. Next, the registration control procedure will be described with reference to the flowchart of FIG. In the flow chart of FIG. 8, an example of the screen of the CRT 4 is illustrated in the step as needed.

After setting the image original to be registered in the optical disk to IS31, specify the registration volume in step S2. This registration volume is the ID (name) of the optical disk. Next, in step S4, in accordance with the instruction displayed on the CRT4, an image reading mode (image file attribute), for example, resolution (=
200dpi / 300dpi / 400dpi), original size (A3, A4, B3, B4)
Is instructed using PD5 via the menu screen. In step S6, the image is read from the IS31 and temporarily stored in the IMEM11 in the WS10 according to the designated attribute. IM
The data stored in EM11 is converted for display by BMU16 in step S8, and then stored in VRAM in CRTIF15 and CRT.
Displayed in 4. The operator visually checks the displayed image and confirms whether the image is properly read. If the image has been correctly read, it is determined in step S12 whether the image just read is one page or the first page of a plurality of pages. This can be easily determined from the operator's instruction or the attribute designation made in step S4. The reason for making such a determination is to set the keyword 66 at the first page. If it is the first page of one page or a plurality of pages in step S12, the keyword 66 is set in step S14, and the input keyword 66 is temporarily DMed.
Stored in EM20. As described above, the keyword 66 is input through the PD5 or KBD6 while visually checking the CRT4. DME
After being stored in M2, the keyword 66 is formatted together with other information as shown in FIG. 4 (b), the search information record is written in HD2 in step S16, and the process proceeds to step S18. If the judgment in step S12 is NO, immediately step S12
Then proceed to step S18. After storing the search information record in HD2, etc., use PD5 to enter WS10 with the end icon.
Is started, and at step S18, the image information temporarily stored in IMEM11 is written to the optical disk via ICU18 and ODIF12.

The above operation is repeated until all pages are completed (step S20).
When all pages are completed, the retrieval information record of the image original is written in the optical disk file 40 as a backup at step S22. At this point, the search information record for image file registration and backup is stored in the optical disk file 40 as shown in FIG. Therefore, even if the search information record of the image information is destroyed in the HD 2 due to some trouble, since the same search information record exists on the optical disk file 40, the restoration can be easily performed.

As other information added to the keyword 66 in the search information record, information on whether the image information is an optical disk or a microfilm, address information of where on the optical disk the image information is stored, size information of A4, A3, etc., resolution information And ICU
The compression etc. in 18, that is, whether the information amount stored in the optical disk and the negative information or the positive information is added to the head of the search information record by the information in the conversation with the operator by the WS10 and the information from the optical disk. To be done.

(Registration from Optical Disk) The above is registration from IS31. However, as described above, it may be possible that a trader or the like registers from an optical disk on which an image has already been written. In this case, the trader may write the keyword 66 in the FPD or the like in the same manner as the image writing in the optical disk. In this case, IS at step S6 in FIG.
Instead of inputting from 31, images are sequentially read from the optical disk, the search information is read from FPD3 in parallel with the image reading, and each time they are read, the keyword 66 is set and the search information is set to HD2. Registration and backup to the optical disk.

<Registration of microfilm file> Regarding microfilm, normally, while reading the microfilm image that has already become a film from MS51, create a search information record including the cartridge number and frame number and register it on HD2. It is a thing. The outline of the operation is shown in FIG. A feature of this embodiment is that the search information record is registered on the HD2 and the search information record for backup is also stored in the FPD3.

FIG. 10 is a flow chart showing a control procedure for microfilm registration. For the operation of the micro film file, the operator first sets the cartridge for each cartridge as shown in FIG. 9 and causes it to be read, and sometimes the automatic cartridge (MA) 52 is used to automatically select the cartridge. . Unlike optical discs, the micro film file registration uses the frame number on the micro film as an absolute address. Therefore, the cartridge number, frame number, etc. are input to the ADD62 added to the search information record to become the search information record. . Also, since the micro film file is a forward file, the same keyword 66
If one search information record is given to a plurality of frames of microfilms that should have, it is possible to reduce the area of HD2.

The control procedure when the MA 52 is not used will be described with reference to FIG. First, in the loading section 54, the microfilm cartridge having the image information for which the keyword 66 should be registered is set, and the image reading mode (image attribute) is set in step S30 in the same manner as the image scanning (IS) input described above. Give instructions. Reading is started in step S32, and the read image information of one frame is temporarily stored in IMEM11.
Displayed on CRT4 in S33. As with the registration from IS31, check whether the reading was successful (step S3
4) In step S36, it is determined whether the image file is one frame or continuous frames. At step S40, the operator gives an instruction for the keyword 66, and at step S42 stores the search information record in the HD2. In step S44, the backup information record is backed up on the FPD3.

For the first image information, the operator indicates the frame number of the microfilm, and if registering sequentially, step A30
WS10 +1 in DD field 62 and 1 in microfilm
It is sufficient to advance the frames, and in order to record the search information of the input image, the frame number is designated each time. one time,
Once registered in HD2, it manages all search information records in HD2, similar to the optical disk mentioned 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 disc file are combined, and the composite image is registered and the search information record thereof. Back-up registration will be described.

First, in step S50 of FIG. 11 (a), an image is input from the microfilm. Next, in step S52, an image is input from the optical disk file 40. Steps S50 and S52 are subroutines, the details of which are shown in FIGS. 11 (b) and 11 (c), respectively. The difference between the subroutines is only the difference in the instruction keyword 66. In steps S72 and S76 of each subroutine, the search subroutine (Fig. 11 (d)) is executed.

In the search subroutine, the search information record having the designated keyword 66 is searched in HD2 (step S80).
The searched search information record is stored in DMEM20 (step S82), and in step S84, DEVID61 in the search information record is stored.
Value determines whether the image is in the microfilm file 50 or the optical disk file 40.

If the value of the identification mark DEV-ID61 is "1", it is determined that the image is recorded in the microfilm file 50, and according to the address information ADD62 of the search data, the corresponding image frame of the microfilm file 50 is recorded. Perform a search (step S86). Then, the image of the frame of the retrieved microfilm is read (step S88). DEV-ID
If 61 is "0", the optical disk file 40 is searched according to the address information ADD (step S90), and the image file is read (step S92).

Microfilm file 50 or optical disk file 40
Image information read from is IM of workstation 10
One page is stored in the EM11 (step S94). This ends the search subroutine.

Returning to step S54 in FIG. 11 (a), the two images in the IMEM 11 are processed. This processing is done by BMU16. If the processed image needs to be registered, the process proceeds to step S60, and the keyword 66 is set in order to create a new search information record. Step S62
Store the processed image in the optical disk file 40 with
A new search information record is stored in HD2 in S64, and a backup copy of the search information record is stored in the optical disk file 40 in step S66. To describe the operation shown in FIGS. 11A to 11D in accordance with FIG. 6, for example, an image file “component” from a microfilm and an optical disc file 40 are used.
This means that a new image file "parts catalog" was created on the optical disk file 40 by synthesizing it with the image file "parts name" (Fig. 12).

In the above description, the combination of the images of the microfilm and the optical disc has been described, but the image transfer from the microfilm to the optical disc is also possible.

<Back up file load> The back up file load is, for example, when the search data on the HD2 is destroyed due to a failure or the like, or during the initial processing of the JOB program in the embodiment described later, from the optical disk file 40 and FPD3. Refers to the operation to reconstruct the search information record on HD2 as shown in Fig. 5. Figure 13 shows the operation concept. FIG. 14 is a flowchart of the control procedure.

According to FIG. 14, first, the optical disk and FPD3 to be restored in step S100 are set in the drive. At step S102, all search information records of the set optical disk are read out and stored on the HD2. This operation is performed on the all-optical disk that needs to be restored. Next, in step S106, similarly, the retrieval information record of the microfilm file 50 is restored from the FPD3. In this way, the search information record can be restored very easily.

<Deletion and restoration of search information records> In the above control procedure, all search information records are restored. However, it is extremely difficult to specify a specific keyword 66 and restore only the search information records with that keyword 66. It's easy. An example of this is the partial deletion of a search information record and the recovery of the deleted search information record from backup. FIG. 15 shows an example of deletion. It goes without saying that the deletion in this case refers to the deletion of only the search information record on HD2. FIGS. 16 (a) and 16 (b) are flowcharts of the control procedure for deleting and restoring the search information record, respectively. To explain the outline of them, the search information record to be deleted first has the keyword 66.
The search information record in the HD2 having the keyword 66 set on the CRT4 is displayed on the CRT4, and the operator deletes the desired search information record (FIG. 16 (a)). The restoration of the deleted search information record is also performed by searching the search information record obtained from the keyword 66 in the optical disk file 40 or FPD3 by setting the keyword 66 (Fig. 16 (b)). .

<Effects of the above embodiment> In this way, the format of the search information record for the optical disk file 40 and the micro film file 50 is common, and the search information records for both files can be stored together in the common HD2. An operator who conducts a search can obtain desired image information by inputting a keyword 66 corresponding to the image to be searched, without considering the search target file of the image. That is, since the file (medium) in which the image is actually recorded in the search information record and the address in the file are managed, the operator does not have to be aware of the composite medium when searching the image, This makes it easy to centrally search for images.

Further, since the backup of the search information is provided in the optical disk or the FPD 3, it is easy to restore the search information, and the management is ensured by distinguishing the backup media. Furthermore, by providing a backup, it is possible to safely delete information that is rarely used or search information that is outdated, so that an empty area on the hard disk can be secured, and a new image information keyword 66 Can be registered.

<Composite image file system with optical disk for backup only> In the image file system described above, the backup information record of microfilm is stored in FPD3 and the backup information record of optical disk file 40 is stored in the optical disk. I was told to be burned. In the composite file system described below, the above-mentioned search information record (including the search information records of both a plurality of optical disks and microfilms) is stored in an optical disk dedicated to backup. The advantages of providing such an optical disk dedicated for backup are as follows. Of course, it is needless to say that the image file can be stored in this back-up dedicated optical disk.

As the scale of the composite file system increases, the number of optical disks and the number of microfilms naturally increase.
In such a case, the optical disk or microfilm to be used is often divided into jobs (JOB) and the optical disk or microfilm dedicated to the job is used. Furthermore, if there are daily or monthly jobs even for the same job, it may be desired to perform the job with the latest date and time or monthly file configuration. Also, there are cases where you want to restart a job on a specific date. The feature of the optical disk is that the image files are accumulated one after another without being updated.

In such a case, by backing up the search information records for each JOB or for each date / time (monthly) to the backup dedicated optical disk, the operator can determine which optical disk and microfilm are required for the job. You don't have to worry, you just need to read and process the search information on the back-up dedicated optical disk. Furthermore, the relevant JO
If you store programs such as B in the optical disk dedicated to backup, you only need to have the initial start program resident in HD2, and you can easily resume the job at the desired time.

Further, as described above, it is indispensable to register the keyword of the image file in the normal image file system. Because of the large amount of registration work, once registered on the HD2, various JOB programs share and use the search information on the HD2. Since it is shared, it is difficult to manage files for each JOB program and each date as described above. In addition, the search information is not systematically stored and is simply stored in the order of registration.

<Outline of JOB program> The optical disk dedicated to backup is proposed based on the above requests. Therefore, in this embodiment, the JOB program of the proposed composite image file system has an outline as shown in FIG. That is, as shown in FIG. 24, in each of the optical disk backup area for the FPD 3 and the image file, the back-up file of the search information of the micro film and the image file of the optical disk is already stored in accordance with the method of the above-described embodiment. It is supposed to be. First, the JOB program copies these backup files on the HD2 as search information used by the JOB program. When the JOB program ends, all the search information on the HD2 will be copied again to the backup optical disk. The backup files copied to the backup-only optical disk are stored as search information belonging to the JOB program. This backup file for each job program is
Each time the OB program is run, it is stored in the backup optical disk one after another. Since the optical disk has a large capacity,
It can withstand the storage of such backup files. To run the same JOB program, retrieve the search information with that JOB program name from the back-up dedicated optical disk in HD2.
The above is called, and the image file is searched and reprocessed according to the search information.

This will be described with reference to the flowchart of FIG. 23. In step S170, the search information storage area on the HD2 is cleared.
In step S172, it is checked whether or not the JOB program is the initial start. If it is an initial start, step
Back up file road mentioned above in S174 (Fig. 14)
The process of is executed. In step S100 of this backup file road, the drive disk and the optical disk required for the job can be loaded into the drive. With this backup file load, the search information for each JOB program is reconstructed on the HD2. Based on this search information, the business process is performed in step S178, and HD2 is processed in step S180.
Copy the latest search information developed above to the backup optical disk (Fig. 20) (details of this flow will be described later). Therefore, when restarting the JOB program, it becomes NO in step S172,
Perform a warm restart (Fig. 22) at step S176. This worm restart is from the backup file on the optical disk dedicated to backup, as described below.
The above is to reconstruct the search information.

<Structure of Back-up Dedicated Optical Disk> FIGS. 17 (a) to 17 (e) show an example of a record format written on the back-up dedicated optical disk.
FIG. 17 (a) shows a format common to each record. In the figure, 70 is a record type. Record type
70 is four types of "0"-"3". Records of each type are shown in FIGS. 17 (b) to 17 (e). FIG. 17 (b) shows a disk type record. The record type 70 of the disk type record is “0”. Disk type 71 is "0"
When the optical disk is, the optical disk is a backup optical disk, and when it is "1", it is the normal optical disk described above.

FIG. 17 (c) is a JOB record. The record type 70 for the JOB record is "1". JO in field 72
The name B is stored in the field 73, the date when the job record is written to the backup-only optical disk, and the field 74 is stored the volume name of the optical disk or the like used for the job. FIG. 17 (d) is a search information record. Its record type is "2". 4th in field 75
The search information shown in FIG. 3B is stored. Figure 17 (e)
Indicates a program record. The record type 70 is "3". If the program is paging or segmented, it can be stored in a backup-up dedicated optical disk with a predetermined record length.

FIG. 18 shows an example of the array of the records shown in FIGS. 17 (a) to 17 (e) in the backup-up dedicated optical disk. The disk type record 80 indicates that this optical disk is a dedicated optical disk for backup, and JOB record 8
The search information record 82 and subsequent items following 1 are all the search information of the optical disk file or the micro film used for the JOB. The JOB program 83 stores the JOB program. The JOB record 84 indicates that another JOB record and search information record are newly added.

<Storing in backup optical disk for exclusive use of backup> Storage of backup files in the backup optical disk for exclusive use of backup is performed in consideration of priority. FIG. 19 (a) shows the number of each drive of the optical disk connected to this composite image file system. The total number of optical disks connected to this composite file system is, for example, 8 at maximum. First
FIG. 19 (b) shows flags in the DMEM 20, showing whether or not the optical disk drive corresponding to each flag is currently used.

FIG. 20 is a flow chart for explaining the order of determining which drive is to be loaded with the backup disk dedicated optical disk under the optical disk configuration of FIG. The optical disk drive is the first requirement for such control of the flowchart.
This is because we consider the usability of the operator when many connections are made as shown in Fig. 19. That is, the WS 10 uniquely determines the drive to which the backup optical disc is to be loaded at the most convenient position as viewed from the operator, displays the drive number on the CRT 4, and prompts the operator to load the backup optical disc.

First, in step S110, check whether all the drives are empty. If all the drives are empty, the message "Load the 0th drive with the dedicated backup optical disk" is displayed on the CRT 4 at step S112. The “0” drive is chosen because it is closest to the operator. "0"
If the backup disk dedicated optical disk is loaded into the drive No. 2, a subroutine for saving to the backup disk dedicated optical disk is executed in step S126. If any optical disk is in use in step S110, check in step S116 if the all-optical disk drive is in use. If all the drives are in use, replace the "0" drive for the same reason to load the "0" drive with the backup optical disk.
And the message is displayed on CRT4. In Step S116,
If any drive is available, identify the drive closest to the operator (the drive with the lowest number), and display the message "Load the drive's dedicated optical disk" on the CRT4. To do. All of the above judgments are made with reference to the flags in FIG. 19 (b).

FIG. 21 is a save subroutine. Step S1 of FIG.
26 details. First, make sure that the optical disk loaded in step S128 is a dedicated backup optical disk. This can be seen by examining the disk type record (Fig. 17 (b)). Set a JOB record (Fig. 17 (c)) in steps S130 to S134, and set a JOB record in step S136.
Write the record on the back-up dedicated optical disk. Then, the search information record (FIG. 17 (d)) and the program record (FIG. 17 (e)) are written in steps S138 and S140. As described above, the point that the search information record of the microfilm is also written is different from the embodiment of FIG.

<Worm restart> What is warm restart? Read the JOB record, search information record, etc. from the back-up dedicated optical disk and use HD2.
The above is expanded and the JOB is restarted. This restart is suitable for a system in which the optical disk or microfilm used for each job is selectively used for each job. The operator of the JOB is J
All search information can be called by the JOB record corresponding to the OB. Since this search information is backed up, it is not necessary to re-register the search information for each job, and the image file system can be used easily. It is also effective when the data on the HD2 is unreliable.

FIG. 22 shows a flow chart of the control procedure for warm restart. This control program is called from HD2 to PMEM9 when it is stored in HD2, but it is stored in advance in a ROM or the like (not shown) in consideration of the fact that the reliability of HD2 cannot be maintained. First, at step S150, the drive number of the optical disk in which the backup optical disk is loaded is designated from CRT4. JO that wants to restart at step S152 after confirming that the optical disk loaded in the drive is a dedicated optical disk for backup (step S151).
B Enter the name and date. A job record corresponding to the job name input in step S154 is searched for in the backup optical disk, and if found, a search information record following the job record is read out on the HD2 in step S156 and expanded. If necessary, the program can also be HD in step S158
2 Read on top and expand. In this way, the search information record can be restored very easily with the desired system configuration that matches the job. The operator can display the volume name in the JOB record on the CRT 4 and know what kind of optical disk and microfilm is needed for the job, and according to the display, prepare the optical disk or microfilm. Good.

<Effects of Embodiment Having Back-up Dedicated Optical Disk> As described above, the image file system having the back-up dedicated optical disk can also store all search information and even a program.

Since the file structure of the image file system can be reconstructed from the copy of the search information managed in the JOB record in the backup optical disk, JOB = file management for each JOB and for each date becomes possible. In other words, it is possible to systematize file management oriented to the JOB program.

[Effects of the Invention] As described above, according to the present invention, there is provided a composite image file system in which file recording devices of different recording forms such as a microfilm and an optical disc are combined, and these recording devices are unified. It is possible to provide a composite image file system capable of file management, reliably maintaining search information that tends to become huge and easily managing the same. Then, further, when the storage means fails by identifying the search information representing the first recording means such as an optical disc according to the identification information included in the search information and storing it in the first recording means. In preparation for this, a huge amount of search information can be surely preserved.
