[Detailed description of the invention] Technical field The present invention relates to an information retrieval system.

BACKGROUND OF THE INVENTION For example, in the medical field, medical face paint information has recently been combined with search information such as a patient's name, date of birth, etc. in order to manage a patient's medical history.

However, because conventional medical image file devices use erasable and rewritable magnetic disks, their capacity is small, resulting in a high cost per bit, as well as the problem of important image information being erased due to erroneous operation. there were.

Purpose of the Invention The purpose of the present invention is to provide an information retrieval system that solves the above-mentioned problems, reduces the cost per bit of recorded information, and prevents important information from being erased due to erroneous operation. It is something.

Summary of the Invention The information retrieval system of the present invention has first and second recording areas where data information and search information corresponding thereto are separated from each other, and the recording area of Izutsu 1 is recorded in a non-erasable area. The present invention is characterized in that corresponding data information recorded in the first recording area is searched based on desired search information recorded in the second recording area.

Embodiment In the first embodiment of the present invention, a non-erasable optical disc is used, image information is recorded on the outer or inner periphery of the disc as a first recording area, and the first recording area and the corresponding disc are separated from each other. Search information is recorded using the inner or outer circumference of the optical disc as a second recording area. Optical disks are accessed by specifying the track and sector stores in the same way as magnetic disks.

Figure 1 shows the data structure of the search information in this embodiment, where the keyword is the name given to each piece of image information, the black track is the track number of the optical disk, the sector width is the first position of the sector, and the data length is the number of sectors. Each recording area is shown. Further, the pointer indicates the area in which to record the next address specified when image information is to be rewritten, and is in a state in which nothing is recorded (Null) when the image information is not being rewritten. That is, in FIG. 1, the keyword rA
BOD, J image information is track shop-1 and sector shop-1
It shows that 64 sectors have been recorded from sector A-65 on track A-1, and image information for keyword l'-'D E F J was recorded on track A-1 for 128 sectors from sector A-65. It shows that 128 sectors from sector number 1 have been rewritten and recorded on track A-No. Note that the image information is recorded in the first recording area together with the track information and the sector information.

A second FgJ shows a configuration diagram of this embodiment, in which an optical disk device 1, an image display device 2, and a console device 8 are each connected to a computer (CPU) 4.

The operation of this embodiment will be explained below.

If there is free space in both recording areas, input the image information to be recorded and the size of the keyword data input via the console device 8, and record the first and second areas in which they were detected. It is determined whether or not there is a person in each free area of the recording area, and if one of them cannot fit, similarly, Disk Full is displayed and the optical disc is replaced. When it is determined that both pieces of information fit into the respective free areas, it is determined whether the keyword has already been recorded, and if it has not been recorded, the search information is transferred to the free space in the second recording area. area and record the corresponding image information together with the track store and sector store in the free area of the first recording area, and if the keyword has already been recorded, the corresponding search information that has already been recorded. After updating the pointer to the address in the second recording area of the search information to be newly recorded, the new search information and the image information corresponding thereto are respectively recorded in the same manner as above.

In addition, when searching for desired image information from an optical disc, all the search information recorded in the recording area of our company 2 is read into the memory in 0PU4, and as shown in FIG. A keyword for information is input from the console device 8, data matching the keyword is searched from the second recording area, and if there is no matching keyword, no data is displayed on the image display device 2, and a match is found. If there is a keyword, then it is determined whether the pointer of the search information is NIJ, 11 or not. When the pointer is determined to be ], u; l l,
From the search information, it can be seen that the desired image information is recorded on which track of the optical disc, from which sector, and with what sector length. Based on this, the desired image information is searched from the first recording area and the image is imaged. It is displayed on the display device 2. Also, when it is determined that the pointer is not Nu-//, the updated address search information recorded in that pointer is read, and similarly the pointer is Huj
It is determined whether or not t.

In this example, a non-rewritable optical disc is used,
In addition, search information is added without being deleted, so important information is not deleted and a large amount of information can be recorded, making the cost per bit of recorded information extremely low. Become. Note that since the error rate of optical discs is approximately 10-6, it is preferable to add error correction to the search information.

In the second embodiment of the present invention, image information is recorded using the optical disc as the first recording area. to allow access. The data structure of the search information recorded on the magnetic disk is as shown in FIG. 1 with the pointer section removed, and when image information is rewritten, the track information, sector information, and data length portions of the search information are rewritten. Further, the image information is recorded together with the track information and the sector information, as in the above-described embodiment.

FIG. 5 shows a configuration diagram of this embodiment, which differs from FIG. 2 only in that a magnetic disk device 5 is newly additionally connected to 0PU4.

The operation of this embodiment will be explained below.

In this embodiment, since the magnetic disk is determined to correspond to the optical disk, it is necessary to check whether both disks are compatible at the beginning of access. First of all,
When recording image information and search information, an optical disk and a magnetic disk are set in the optical disk device 1 and the magnetic disk device 5, respectively, and under the control of the CPU 4, the IDs of both disks are set as shown in FIG. The numbers are read and it is determined whether or not they match. If they do not match, the image display device 2 displays the discrepancy, and if they match, it is then detected whether or not there is a free area on both disks. Dis if there is no free space on either disk.
k Full is displayed, and if there is free space on both disks, enter the image information to be recorded and the size of the keyword data input via the console device 8, and select whether they are the optical disk or magnetic disk, respectively. Determine whether or not to enter the detected vacant area.
If either one is not needed, DiskFu
Display ll. When it is determined that both pieces of information fit into the respective free areas, it is determined whether the keyword of the search information has already been recorded in the magnetic disk device 5, and if it has not been recorded, the search information is stored on the magnetic disk. At the same time, the corresponding image information is recorded in the empty area of the optical disk along with the track record and the sector grave, and if the keyword is already recorded, the corresponding search information that is already recorded is recorded in the track store and the sector. The image information is rewritten to the image information to be newly recorded, and the image information is recorded on the optical disc.

In addition, when searching for desired image information from an optical disc, the ID numbers 4jfH of both discs are first displayed to determine whether they match or not, and if they do not match, a message to that effect is displayed.
If there is a match, the keyword for the desired image information to be searched for next is input from the console device 8, and the CPU
Under the control of 4, data matching the input keyword is searched from the magnetic disk, and when there is no matching keyword, no data is displayed on the image display device 2, and when a matching keyword is found, the search is performed. Based on the information, the corresponding desired image information is retrieved from the optical disc in the same manner as in the above-described embodiment, and is displayed on the image display device @2.

In this embodiment, since the search information is recorded on the magnetic disk, it is possible to rewrite it, and therefore the space of the recording area can be used effectively. Therefore, hardware costs can be reduced.
