Abstract

PURPOSE:To share an optical disk among plural systems by writing the retrieval data group for retrieval of image data of the optical disk on this disk without permitting the residence of said retrieval data at a retrieval control part. CONSTITUTION:When image data 7 is registered on an optical disk 8, the data 7 is transferred to an image control part 4 from an image information input part 2. While the retrieval data 6 corresponding to the data 7 is transferred to a retrieval control part 3 from a retrieval information input part 1. The data 6 and 7 are transferred to an optical disk control part 5 from the parts 3 and 4 respectively. The part 5 combines both data 6 and 7 and writes them on the disk 8. The data 6 written on the disk 8 are all read in a system rise mode and sent to the part 3. Then a desired one is retrieved out of those retrieval data groups.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a search data control method for an information storage system using an optical disk.

〔overview〕

The present invention provides a search data control method that defines a procedure for registering search data related to information on an optical disk, in which the search data is set in a state where the data is read out without being resident in the storage means. By registering the search data in the storage means before reading from the optical disc, the storage means can be shared by a plurality of optical discs.

[Conventional technology]

In the conventional search data control method, only document image data is written on an optical disk, and a search data group for searching the image data is resident on a magnetic disk or the like in a search control section.

[Problem that the invention seeks to solve]

In such a conventional method, if a search data group of a specific information storage system is resident in the search control unit, an optical disk can be shared by a plurality of state storage systems.

I can't. On the other hand, when controlling search data groups of a large number of optical discs, the search control section has the disadvantage of requiring a large-capacity storage device.

The present invention aims to eliminate this drawback, and aims to provide a search data control method that allows searches to be executed smoothly using a small-capacity storage device.

[Means for solving problems]

The present invention relates to an information processing system comprising optical disk control means for combining optical disks and reading information from the combined optical disks, and storage means for registering search data related to reading this information. , is a search data control method that defines a procedure for storing search data in the storage means, and as a means for solving the above-mentioned problems, the search data related to this information is registered on an optical disk together with the information, and the control means The present invention is characterized in that the search data registered on the optical disc coupled to the optical disc is transferred to the storage means.

[Effect]

When registering information, search data is also written to the optical disk together with this information, and each time the optical disk is replaced, the search data is transferred to a storage means and reading from the optical disk is controlled based on this search data.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example apparatus in which the method of the present invention is used will be described below with reference to the drawings. The figure is a block configuration diagram showing the configuration of the apparatus of this embodiment. The apparatus of this embodiment includes a search information input section 1, an image information input section 2, a search control section 3, an image control section 4, an optical disk control section 5, and an optical disk 8.

Next, a procedure for registering document image data and a procedure for transferring search data when starting up the system or replacing an optical disk will be explained based on the drawings. At the time of registration, image data 7 is transferred from the image information input section 2 to the image control section 4. Further, search data 6 corresponding to image data 7 is transferred from search information input section 1 to search control section 3.

Subsequently, search data 6 and image data 7 are transferred from search control section 3 and image control section 4 to optical disk control section 5, respectively. By the optical disk control unit 5,
The transferred search data 6 and image data 7 are combined and written onto the optical disc 8. Registration is performed by repeating the above steps. Also, when starting up the system or replacing the optical disk, the optical disk control unit 5
All the search data 6 written on the optical disk 8 at the time of registration is read and transferred to the search control section 3.

The search control unit 3 rearranges the transferred search data 6 to construct a search data group. When searching, desired search data is extracted from this search data group, and the corresponding image data is read from the optical disc 8.

〔Effect of the invention〕

As explained above, the present invention does not make the search data group resident in the search control unit but writes it to the optical disk.
This has the effect of allowing multiple systems to share an optical disk.

Furthermore, when controlling a large number of optical disks, there is no need to permanently store search data groups for all optical disks, and only the connected optical disk devices need to be maintained.
Another effect is that the capacity of the search control unit storage device can be reduced.
