In such an electronic file system, it is possible to divide a plurality of pieces of information for such a search into one piece of image information, and use each piece of information to select a plurality of search operations. is there. For example, in the technique disclosed in Japanese Patent Laid-Open No. 59-038845, each data is provided with two types of search information having different search procedures, and the operator selects and uses the search information. The search process can be performed efficiently.

However, in such a technique, it is necessary to provide an area for recording all search information on the optical disc. Therefore, depending on the user, an area for a search operation that is not used is also provided on the optical disc, resulting in a useless area on the optical disc. Further, in the electronic file system, the search information is read from the optical disk to a storage device such as a hard disk device that can be accessed at high speed, and when searching for image information, the search is performed via this storage device. There are cases. In such a case, even search information that is not actually needed is transferred from the optical disk to the hard disk, which causes a drop in performance.

[0004]

The problem to be solved is that in the prior art, an area for search information that is not actually used is provided on the optical disc, and the recording capacity of the optical disc is unnecessarily reduced. That is the point. An object of the present invention is to solve these problems of the prior art, avoid use of the area of the optical disk due to useless search information, effectively use the capacity of the optical disk, and increase the transfer of search information to a storage device for search. An object of the present invention is to provide a format setting control method for an optical disc, which enables efficiency improvement.

[0005]

In order to achieve the above object, an optical disc format setting control method according to the present invention comprises: (1) selecting one from a plurality of retrieval operations to retrieve image information recorded on the optical disc. In the electronic file system that performs
It is characterized in that an area having a size used for recording search information corresponding to the only search operation selected and specified by the operator is set.

[0006]

In the present invention, when setting the format of the optical disk, the operator records only the search information used for the search operation actually performed. This makes it possible to reduce the recording area for search information, and as a result,
The area for image information to be recorded on the optical disk becomes large, and more image information can be recorded.

An optical disc for recording the image information input by the input device 3 and the search information input by the input device 2 in association with each other. Reference numeral 6 denotes an optical disc device for controlling the read / write operation of the optical disc 5,
An information processing apparatus 7 controls the operation of the electronic file system.

The information processing device 7 includes control of peripheral devices such as the display device 1 and the optical disk device 6, and a main controller 8 for controlling the processing of the entire information processing device 7 and a search input by the input device 2. On the basis of the conditions, the corresponding image information is specified from the hard disk device 4, the search processing unit 9 for searching the image information recorded on the optical disk 5 via the optical disk device 6, and the initialization processing of the optical disk 5, An optical disc format setting control unit 10 for controlling the format setting of the optical disc 5 according to the present invention is provided in response to a search operation selected and inputted by the operator via the input device 2.

The operation of the format setting control of the optical disk 5 of the present invention in the electronic file system having the above-mentioned structure will be described below with reference to FIG. In this embodiment, it is assumed that there are two types of search operations.

In FIG. 2, when the operator sets a new optical disc 5 in the optical disc device 6 and gives an instruction to initialize the optical disc 5 via the input device 2 (step 101), the information processing device 7 The optical disc format setting control unit 10 causes the display device 1 to display selection guidance of two search operations that can be selectively recorded (step 1).
02). Then, the operator waits for selection by the input device 1 of FIG. 2 for the two search operations displayed on the display device 1 (step 103). When the first type of search operation is selected, the information processing device 7 of FIG. 2 controls the optical disc device 6 of FIG. 2 by the optical disc format setting control unit 10 of FIG. 2 to select the selected first type. The optical disk 5 of FIG. 2 is initialized with a format having an area for recording search information used for the search operation (step 104).

In the present embodiment, the image information 31a-3.
1c includes search information A32a to 32c and search information B33a.
It is possible to select and add any one of the search information items up to 33c. Thus, for example, when only one search operation is always used, the operator records only the search information necessary for the search operation on the optical disc, and therefore the search secured at the time of initialization of the optical disc. The area for storing information is only required to store the search information necessary for the search operation. For example, if it is known that the operator only performs the search using the first type of search information A32a to 32c, only the area for storing the first type of search information A32a to 32c is stored on the optical disc. All you have to do is secure.
