Abstract

PURPOSE:To store enormous materials by providing an optical medium control file, a position control file and a retrieving information file and retrieving image data with a registering number and retrieving information as a key. CONSTITUTION:A retrieving system is composed of a retrieving information file 1, a position control file 2, two optical media 3 and 4 and an optical medium control file 5. The optical medium control file 5 records information to show the device position of an optical disk medium which is mounted to plural set optical disk devices. The retrieving information file 1 stores the registering number, the retrieving information and corresponding information with the specified area of the position control file 2. By designating the registering number and retrieving information, the specified area of the position control file 2 is determined from the stored contents of the retrieving information file 1 and the stored position of the image data can be known by the contents. Thus, since the optical medium of large capacity is used, the enormous materials can be stored.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image data retrieval system, and more particularly to an image data retrieval system using a collective optical disk.

[Conventional technology]

Because of their large capacity, collective optical disks are suitable for storing vast amounts of data such as image data. However, since it was originally developed for sequential files, special means are required for random access.

A conventional image data retrieval system using a collective optical disk does not have such special means, and is optimized as a dedicated image system using a single collective optical disk device.

[Problem to be solved by the invention]

The above-mentioned conventional image data retrieval system has limitations in terms of the capacity of the source medium and in large-scale networking, and has the disadvantage that system services can only be provided within a limited range (utilizing locations and capacity).

Furthermore, since it is an image-only model, code data other than images (index information, etc.) cannot be used effectively in other systems.

[Means to solve the problem]

The image search system of the present invention includes: an optical medium management file storing information indicating the device position of the optical disk medium in the collective optical disk device group; and a storage position of image data stored in the optical disk medium and marked with a registration number. A location management file that stores the image data as an optical disk medium name and address within the medium, and an index information file that stores the registration number and index information, so that the image data can be searched using the registration number and index information as keys. It is characterized by the following.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, which includes an index information file 1, a location management file 2, two source media 3 and 4, and an optical media management file 5.

The optical medium management file 5 records information indicating the device positions of optical disk media loaded in a plurality of collective optical disk devices (not shown).For example, the source medium VOL 2 is the collective optical disk with the device number "1". Within the range shown in the diagram, the collective optical disk device with the device number “1” has the source medium VOL.
It can be seen that three optical disc media, VOL 1, VOL 2, and VOL 3, and two optical disc media, VOL 4 and VOL 5, are installed in the collective optical disc device with the device number “2”.

Note that the optical medium management file 5 has status information for managing the usage status of the source medium in the volume status column, such as used and currently in use.

The unused state is updated every time an image is written to the source medium. In addition, the type of image (drawings, specifications,
The image data classification column has classifications for classifying general documents, etc.).

The location management file 2 records the storage location of each image data stored on the optical disk medium and determined by the registration number 1 version number and page.
The version number "1" indicates that the image data of the third page is stored in the storage location C. That this image data exists on source medium 3 rather than source medium 4 can be understood by referring to the detailed diagram of the location management file shown in FIG.

In FIG. 2, the image data group determined by the registration number and version number has a source medium name, file name, and address specified for each page. In this case, the file name is given to each of the plurality of files provided in the source medium.

Referring again to FIG. 1, the index information file 1 indicates that the association between the registration number, the index information, and the specific area of the location management file 2 stores information. The registration number is the main key for searching the location management file 2, and the index information is the subkey for version number, page, etc. Index information file 1 is formed on a relational database.

From the above explanation, the image data search procedure can be easily understood. That is, by specifying the registration number and index information, the specific area of the location management file 2 is determined from the storage contents of the index information file 1, and the storage location of the image data can be determined from the contents.

〔Effect of the invention〕

By adopting the configuration described above, the present invention can connect collective optical disks to general-purpose computers and establish a management system for image processing, making it possible to use large-capacity source media and store vast amounts of data. . In addition, through networking, many departments can share common materials (image data).
Since it is centrally managed, index information can be used in other systems.
