400 is a display means for displaying the management data searched by the search means.

When reading the recorded information of the optical disc, 500 confirms that the optical disc with the input disc name is loaded in accordance with the input of the file name and disc name from the input means, and then performs the management. The optical disc is an information reading means for reading recording information of the input file name from the optical disc based on recording position information of the storage medium.

600 is capable of updating the content of the management data stored in the management storage medium using the input means, and when the content of the management data in the management storage medium is updated, the update is performed. Management data updating means rewrites the contents of the data recorded on the target optical disc after confirming that the target optical disc is loaded.

FIG. 2 shows the system configuration of an embodiment of the present invention.

In FIG. 2, reference numeral 1 denotes a central processing unit (CPU), which executes the control procedures shown in FIGS. 5 to 10 to perform various control processes for recording/reproducing information on an optical disc. Old cp is the main search method.

It functions as a reading means and a management data updating means.

A keyboard 2 serves as an input means for inputting operation instructions and information to the CPU. Reference numeral 3 denotes a display device as a display means for displaying input/output information for the CPUI, and in this example, a cathode ray tube (CRT) display device is used.

Reference numeral 4 denotes an optical disc recording/reproducing device, which performs IA processing (reading, reproducing) and writing (recording) information on the optical disc according to instructions from CPt1l.
Although the mechanical and circuit configurations of the playback device 4 can be conventionally known, it is different from the conventional device in that the storage address of the information stored on the optical disk is stored in the magnetic disk storage device 5, which will be described later. different.

5 is a magnetic disk device as a storage means for storing directory information such as a disk name of an optical disk, an information storage address, a file name, etc. on a magnetic disk;
Instructions for reading and writing information are given. Instead of a hard disk, a floppy disk or a non-volatile memory storage device may be used, and the desired storage device may be selected depending on the size of the system and the amount of information to be handled.

Reference numeral 6 denotes an interface that receives information to be stored on the optical disc, such as image information, from an external device and transmits image information read from the optical disc to the external device.

In this example, image information is received from the imaging device.

FIG. 3 shows the address structure of the magnetic disk storage device 5 shown in FIG.

In FIG. 3, the storage area for storing record information at one address on the magnetic disk is divided into the following areas. That is, file name storage area 41, disk name storage area 4
2. Storing a shooting date information storage area 43, a file address storage area 44, a file capacity storage area 45, a first to nth keyword information storage area 46, and attribute information indicating the presence or absence of a file name or disc name change request. Area 4
7 and an area 48 for storing the disk salt and file name before change are provided.

When new information is recorded on the optical disc, the various types of information mentioned above are stored in the corresponding storage area according to cpux instructions.
1 is included. Furthermore, based on the above-mentioned information, a search process for information to be read from the optical disc and a keyword information search process are also performed using cput.

FIG. 4 shows the address structure of the optical disc.

In FIG. 4, the optical disc storage area is divided into a directory area A and a data area B in advance. In the directory area A, 51 is an area for storing disc-related information such as a disc name, a disc manager's name, and the date and time of disc creation, and 52 is a blank area for adding a changed disc salt. Note that in order to back up the magnetic disk storage device 5, the magnetic disk storage device 5 is attached to the optical disk.

Reference numeral 56 denotes an area in which address information indicating the beginning of a writable blank area is stored for each disc name.

In the conventional example, the address to be read from the data area B is detected based on the storage information in the directory area 55, but in this example, the directory information stored in the hard disk storage device 5 is used for data reading, and the storage information in the directory area A is detected. It functions as a backup of directory information in the hard disk storage device 5. Note that if saving memory capacity is important, it is not necessary to provide the directory information area 55 and file name storage area 53.

Next, the operation of the circuit shown in FIG. 2 will be explained with reference to the flowcharts shown in FIGS. 5 to 1O.

FIG. 5 shows the main control procedure executed by CPIJI.

In Figure 5, when the system is powered on, the CP
A processing menu is displayed on the CRT 3 (see FIG. 2) by H (step 5100). In this example, information writing processing, information reading processing, information searching processing, and search-related information registration processing are prepared. Then, the operator selects and inputs the desired process from the keyboard 2. In response to this selection input, the @control procedure shown in FIGS. 6 to 1θ is executed.

In addition, regardless of the operator's instructions, when an optical disk is inserted into the optical disk storage device 4, a process is performed to automatically register a changed file name or a changed disk salt on the optical disk based on the storage information of the magnetic disk storage device 5. CPIJI
The interrupt is executed (step 5600).

Hereinafter, various processes of this embodiment will be explained according to the control procedure shown in FIG.

When the operator selects the instruction to store information (step 5200 in FIG. 5), the control procedure shifts to the write processing procedure shown in FIG. 6.

In FIG. 6, the CPIJI receives a file name and file name search information, such as keyword information, input by the operator through the keyboard 2h1, and the CP
Temporarily store in the work register in IJI (step 5)
202).

Next, CPt1l instructs the optical disc recording/reproducing device 4 to read the optical disc name. Next, based on the read disk salt, a write start address is read from the magnetic disk of the magnetic disk storage device 5, and the disk salt is displayed on the CRT 3 (step 5203).
.

Next, set the recording start address to the optical disc recording/playback device 4.
At the same time, transmission permission is given to the imaging device via the interface 6. Image information sent from the imaging device is sent to the optical disk storage device 4 via the interface 6, and sequentially written to the optical disk by the optical disk storage device 4 (step 5205).
.

Since the image information transfer process and the write process of the optical disc device 4 are well known, a detailed explanation thereof will be omitted.

At the same time as the CPUI performs image information transfer processing, the capacity of the information is counted.

When the reception of the image information from the imaging device is completed, the write start address is updated by the amount of information, and the file name stored in the work register, the counted amount of information, and the write address are sent to the optical disk recording/recording from the CPUI. The data is sent to the playback device 4.

As a result, new directory information and file names are created in the directory area A of the optical disc recording/playback device 4. Subsequently, search-related information to be written in each of the memory areas 41 to 46 shown in FIG. 3 is sent from the CPt1l to the magnetic disk storage device 5 in addition to the above-mentioned directory information, and new file information is created on the magnetic disk.

When the above writing process is completed, the control procedure returns to step 5300 in FIG. 5.

Next, information reading processing from an optical disc will be explained.

An instruction to read stored information and a file name to be read are input from the keyboard 2 or from an external device via the interface (steps 5100→5200→5).
300), the procedure shifts to the control procedure shown in FIG.

In Figure 7, the CPUI changes the input file name to C
Store in the work register in Pu, then read the disk salt from the optical disk (steps 5302-5303)
.

Based on this disk name, the file name stored in the work register, and the file information on the magnetic disk, the CPIII confirms that the input file name exists on the installed optical disk and magnetic disk (
Steps 5304→5305), the CPU reads the storage address of the corresponding file name from the magnetic disk,
The read address of this file information is instructed to the optical disc recording/reproducing device 4.

Thereafter, the information read from the optical disc recording/playback device 4 is displayed and input to the CRT 3 (steps 5306→53
07).

Next, information search processing according to the present invention will be explained.

When the operator selects a search process from the keyboard 2 while the menu screen is displayed, the CPU control procedure shifts to the control procedure shown in FIG. 8 (steps 5100 to 5 in FIG. 5).
400→control procedure in FIG. 8).

In FIG. 8, first, a search menu prepared in advance is displayed on the CRT 3 using the CPU.

The following processing is possible as the search processing.

(1) Searching for file names using optical disk salt (2) Searching for disk names using file names (3) Searching for file names using keyword information (4) Displaying a list of stored contents.

For example, in a search using optical disc salt, the CPU extracts file name information with the same disc salt as the disc name input by the operator from the hard disk (steps 5420→5421), and in a file name or keyword search, the search target is Since the only difference is that the search process uses the same procedure as described above.

In addition, to display a list of stored contents, the record information sequentially read from the first address of the magnetic disk is displayed on the CRT 3 by the CPU (steps 5450→5451).
.

Even if the operator forgets the file name, he or she can know the desired file name by inputting various keywords, disc name, file name, and related information. Also,
A desired file name can be easily remembered simply by looking at the list of file names on the hard disk.

Next, the search related information registration process will be described.

When the operator selects and inputs the registration process while the menu screen is displayed (steps 5100 → 5200 → 530 in FIG.
0→5400→5500), the control procedure shifts to the control procedure shown in FIG.

In FIG. 1O, a menu screen is displayed on the CR7 display device 3. The menu screen displays messages that can be registered, that is, registration of optical disc keyword information and changes to various information, along with numbers (step 5502).

The operator inputs instructions to register keyword information using the number from the keyboard 2, and then inputs the file name to be registered,
Entering that disk salt and keyword, CPt
In step 1l, record information having the input disk salt and file name is read from the magnetic disk, and it is confirmed that there is no keyword information that is the same as the input keyword information in the record information. Subsequently, record information obtained by adding the input keyword information to the read record information is written and registered again at the same address on the magnetic disk (steps 5503→5504→5505).

For example, when the modification of a file name is selected and the file name before modification, the new file name to be modified, and the identification name of the optical disk are input via the keyboard 2, the CPI
JI confirms that the new file name is not already in use by referring to the contents stored on the magnetic disk.

Next, the file name before the correction of the corresponding record information on the magnetic disk is rewritten with the new file name, and the old file name before the change is rewritten in the name storage area 48 (third
(see figure). Note that if the optical disc to be modified is not installed, bit "1" is set in the change request club in the record information (step 5506→
5507 → 5508 shout 55011-2).

When an optical disk is loaded, the corresponding file name and other related information on the optical disk and hard disk are rewritten. In this example, when changing the file name or the identification name of an optical disk, there is no need to insert the corresponding optical disk into the optical disk recording/playback device. When the disc is loaded into the optical disc recording/playback device 4, the directory information on the optical disc side is automatically modified by an automatic modification processing program to be described later.

Further, when an instruction to modify keyword information is input, the corresponding keyword information is changed in the same manner as changing a file name in steps 5507→5507-1. Also, if you are instructed to modify the disc name,
Needless to say, all record information with the pre-correction identification name in the magnetic disk is extracted and the new disk name is rewritten.

Next, automatic correction processing for optical discs will be explained.

If the process of changing the file name and disk name described above on the magnetic disk side is executed in advance without installing an optical disk, the control procedure will be as shown in Fig. 1θ every time an optical disk is installed in the optical disk recording/playback device 4. The control procedure proceeds to the control procedure shown in FIG. 5 (step 5600 in FIG. 5→step 5601 in FIG. 10).

Note that there are various known methods for detecting that the optical disc is positioned at a predetermined position using a limit switch, a photosensor, etc. for detecting the mounting of the optical disc, and it is preferable to use these known methods.

When the CPU detects that the optical disc is inserted, the CPU reads out the disc salt and file name from the optical disc via the optical disc recording/playback device 4 (step 5601 N5).
602), stored in an internal register within CPIJI.

Next, the record information whose change flag is set to "1" is read from the magnetic disk by the CP old via the magnetic disk storage device 5 (step 5803).

Next, the file name and optical disk salt before this record information change are extracted. The CPt1l executes a process to determine whether or not the optical disc name before the change matches the current optical disc salt stored in the internal register, and only when the judgment is affirmative, the disc salt after the change in the record information is determined. Optical disk storage @52 (see Figure 4)
and changes the current identification name of the optical disc (steps 5604→5605).

Next, the CPU performs a match comparison between the file name read from the optical disk and the file name read from the magnetic disk, which is stored in the CPU's internal register.
Only in the case of a positive judgment, the file name to be changed is written to the corresponding file name storage area of the optical disk (step 5).
606-5607).

When at least one of the disk name change and file name change processing is completed, the CPUI changes the change flag in the currently read record information to indicate that the change has been completed.
0'' and write again to the same address on the magnetic disk (step 5808).

Thereafter, the next record information whose change flag is "1" is read, and the disc name change process and file name change process on the optical disk side are executed in the same procedure as described above (steps 5603 to 5609 → 5603). .

When the collation process for all the record information for which the optical disk salt and file name change flag for the currently loaded optical disk are set to "1" is completed (step 5609), the control procedure proceeds to step 510 shown in FIG.
Returns to the initial state of 0.

In this embodiment, the changed disk salt and changed file name can be registered on the magnetic disk without loading the optical disk into the optical disk recording/reproducing device. In this case, when the optical disc is loaded into the optical disc recording/playback device, automatic correction processing of the disc salt and file name is first performed (steps 5100 → 5200 → 5300 in FIG. 5).
→5400→5500→5aoo).

Therefore, the operator does not need to search for the corresponding optical disc when storing it to modify the disc salt and file name, but only needs to give a change instruction from the keyboard 2. Note that when an optical disc is installed and a change in the identification name or file name of the optical disc is registered on the hard disk, at this point, the disc identification name on the optical disc side is changed by the registration process control procedure (step 5508-1 in Figure 9). and file names are corrected.

As explained above, in this embodiment, by storing various management information regarding general information (file information) stored on an optical disc in a non-volatile storage medium separate from the optical disc, keyword search, disc salt, file information, etc. Executes automatic name correction processing.

Furthermore, even if an optical disc is damaged, as long as the disc salt is known, the file name stored on the disc can be known.

Possible applications of this embodiment are as follows.

l) In this embodiment, an example was shown in which a file is searched using keyword information as a key, but a disk salt can also be used as a key. In this case, the disk salt is treated as one of the keyword information.

2) In this embodiment, keyword information is input directly from the keyboard 2, but it is also possible to input keywords in the following embodiment. That is, a large number of keywords are numbered and stored in a read-only memory (ROM) in the form of a table in advance, and when entering a keyword, the keyword table is displayed on the CRT 3. Next, by moving the cursor on the keyboard 2, etc. Keyword input is performed by specifying the number of the desired keyword. In this case, the keyword information stored on the hard disk is in the form of numbers, so the keyword information can be expressed as a code of several bits, forming a code. The number of bits can be reduced.

3) In this embodiment, the change flag storage area in the magnetic disk is made up of 1 bit, and areas for storing the disk salt and file name to be changed are provided in the hard disk, but the change flag is made up of 2 bits. When the information to be configured or changed is a disk name, it is "1"' (1O decimal number), when it is a file name, it is "2" (decimal number), and when the disk salt and file name are to be changed, it is "3" (decimal number). If the change flag value indicates the type of information to be changed, the number of areas to store the name before change is only one, and both the file name and disk salt are stored in this storage area. be able to.

4) In this embodiment, the keyword search is executed based on the information stored in the magnetic disk storage device 5, but if the optical disk has backup information, the storage information on the optical disk can be restored in the event of a failure of the magnetic disk storage device. Based on the information, keyword searches can be performed.

〔Effect of the invention〕

As described above, according to the present invention, in the first embodiment of the present invention, when recording input information on an optical disc, the file name of general information is added to the optical disc along with the disc salt, recording position information, and keyword information. Since it is stored in a separate management recording medium, the file name can be searched and output from this storage medium by keyword search. As a result, there is no need to load an optical disk into the optical disk device each time for disk search or file search, and the operating labor of the operator is greatly reduced. In addition, since the recording position information of the storage medium is referred to when reading recorded information, it is possible to read the recorded position information faster than reading recording position information from a conventional optical disc, and reading recorded information is faster than conventional optical discs. It will be faster than the example.

In the second embodiment of the present invention, the management information is stored on the optical disk as a backup, so that the information storage property is even higher than in the first embodiment.

In the third embodiment of the present invention, the method of the first embodiment is made applicable to the device, so an optical disc information search function is added to the optical disc recording device, which conventionally only recorded/reproduced information. Therefore, it is possible to perform a variety of searches without having to install a disc, and the operating effort of the operator can be significantly reduced.

In the fourth embodiment of the present invention, when the disk salt of the management storage medium is changed, the disk salt of the optical disk itself is automatically rewritten when the corresponding optical disk is loaded, so the operator can change the disk name. No need to search for the disc every time.
