Abstract

PURPOSE:To efficiently perform the processing of data retrieval and registration by moving the management information of an optical disk from a magnetic disk to the optical disk, integrating data main body and the management information and moving the management information from the inside of optical disk to the magnetic disk in using at other devices. CONSTITUTION:Image data is read from a scanner 21 through a controller 22. It is temporary-stored through an interface 24 to an image buffer 23 and written through a controller 27 to an optical disk 28. Then, prepared various management information is written through a controller 29 to a magnetic disk 30, updated and deleted. To use the optical disk at other devices, after the whole management information is read from the disk, written to the disk 28 to carry out and integrated, the information is deleted from the disk 30 and carried out. In carrying in, after carrying-in items are selected from the menu of a display device 26 and a carrying-in condition is checked, all the various kinds of management information in the optical disk 28 is moved to the magnetic disk 30. It can be used as shared resources with the information of the optical disk by this constitution.

Description

TECHNICAL FIELD The present invention relates to a method for moving optical disk management information, and particularly to a method for moving optical disk management information suitable for using information on an optical disk in other devices, etc. in an electronic filing system.

BACKGROUND ART Conventionally, electronic filing systems have been used as mass storage systems for electronically storing information such as documents containing a mixture of character data and image data (hereinafter referred to as image data). This electronic filing system has an optical disk device, inputs image data from an image scanner, etc., and inputs image data from an optical disk controller (ODU).
) writes the image data under the control of
The optical disk controller reads image data from the optical disk device and displays it on a display device (for example, a CRT display) via a bus.

Among the above-mentioned optical disc devices, write-once type devices are quite popular. However, it is not possible to physically rewrite (rewrite in the same place where the data has been written -) and the time to read/write 1 is slow.

Therefore, directories (management information) that are frequently updated are often stored on a magnetic medium such as a magnetic disk, rather than on an optical disk, and the data main body and the control section are often handled on separate media.

With such a management system, when using an optical disk in another system, it is necessary to transfer the management information held on the magnetic disk as well. Furthermore, there is a method of automatically saving the directory of an optical disk at any time, regardless of whether the optical disk has a directory or not. However, this method has the problem of reducing performance and reducing the user area within the optical disc.

OBJECTIVES An object of the present invention is to solve such conventional problems and provide a method for moving optical disc management information that allows optical disc information to be used as a shared resource in various electronic filing systems.

Structure: In order to achieve the above object, the method for moving optical disk management information of the present invention is an electronic disk drive having a write-once type optical disk device for writing image data, and a magnetic disk device having management information for the image data (latest builf 1 edge). In the filing system, when the optical disk medium on which the image data is written is desired to be used in another system, means for moving and storing management information (latest builf 1 edge) on the magnetic disk medium to the optical disk medium to be used; Management information stored on the optical disk medium (a.
The present invention is characterized in that the storage means includes means for storing the management information on the optical disk medium, and then the management information on the magnetic disk medium is deleted.

Hereinafter, the configuration of the present invention will be explained in detail using examples.

FIG. 3 is a flowchart of the process of writing to the optical disc 28 of FIG. Hereinafter, normal processing will be explained according to the flowchart shown in FIG.

First, image data is read from the scanner 21 by the scanner controller 22 (step 301). Next, the read image data is temporarily stored in the image buffer 23 by the image buffer interface 24, and written from this image buffer 23 to the optical disk 28 by the optical disk controller 27 (step 302). At that time, directories etc. that are created are managed. Information is written to the magnetic disk 30 by the magnetic disk controller 29.

In the above manner, data is written to the optical disk 28,
The management information is stored in the magnetic disk 30.

Changes such as additions, updates, and deletions are made. In case the magnetic disk becomes defective, it is sometimes necessary to save the management information of the magnetic disk to an optical disk.

FIG. 1 is a processing flowchart for explaining a method for moving optical disc management information according to an embodiment of the present invention. When the optical disk 28 is used in another device (system), the management information in the magnetic disk 30 is transferred to the optical disk 28, and all data, directories, and code management information are stored on the optical disk 28 (integrated). do). This process (export process) is shown in FIG. 1(a).

Further, in other devices (systems), the management information is stored in the magnetic disk of that device from the optical disk 28 in which all the information is integrated and used. This process (carry-in process) is shown in FIG. 1(b). These processes are executed by the optical disk take-out/take-in system 32 shown in FIG. Here, disconnecting an optical disk used in a device (system) from that system is called "exporting an optical disk" (deletion from the system), and the removed optical disk can be used in another device (system). This process is called ``bringing in an optical disk'' (registration to the system 8). The following is the process for taking out optical discs,
The import process will be explained separately.

(i) Optical disc removal process First, select the item "Optical disc removal" from the operation guidance (menu) screen displayed on the display device 26 (step 101). Next, from among the plurality of optical disks registered in this system, the user selects which optical disk to take out from the list of optical disks (step 102). Part of the management information of the selected optical disc will be displayed on the display screen, and you will be asked to "Export" (delete) it.
Confirm that it is OK to do so, and proceed with the process.

"Optical disc removal processing" is performed.

In this process, the magnetic disk controller 29 first reads directory information, management information such as index information, and code information such as search information related to the optical disk to be taken out from the magnetic disk 30 (step 103).

Next, write the read information to the optical disk to be exported (
Step 104). After that, those management data in the magnetic disk 30 are deleted and erased (step 1).
05).

(ji) Processing of bringing in an optical disc First, select the item "Bringing in an optical disc J" from the operation guidance (menu) screen displayed on the display device 26 (step 111). Check that it has not been imported (exported) to the system (
Step 112). Then, all the management information, code information, etc. written in the optical disk during the export process are transferred to the magnetic disk (steps 113 and 114).

In this way, in this embodiment, the management information of the optical disk is moved from the magnetic disk to the optical disk, the data body and its management information are integrated, and other devices (systems)
When used in the optical disk, management information is transferred from the optical disk to the magnetic disk, so processing such as data search and registration can be performed efficiently.

Effects As explained above, the present invention has the following effects.

■ Since all related information can be stored within the optical disk, the data on the optical disk can be used as a shared resource by a variety of devices (systems).

(Directories on magnetic disks improve processing performance for data searches, registration, etc.)

■ Since the management information can be saved on an optical disk, the optical disk becomes a bank amplifier for the magnetic disk.
