In the above structure, when a search request occurs, a parameter for search is created. The directory to be the database is searched, the optical disk name and the optical disk address are obtained, and the parameters are set. The parameters are classified by optical disc name, and the parameters are divided when the optical discs are separated so that a plurality of search programs read different optical discs.

After that, the search program is activated by the number of divided parameters as described above, the divided parameters are stored in a plurality of parameter files, and the optical disks set in the plurality of parameter files are searched. Data is extracted and output to an extracted data file corresponding to multiple parameter files. Then, the merge processing means integrates and outputs the data of the extracted data files.

Next, the operation of the optical disk retrieval apparatus of this embodiment will be described.

First, when a search request is generated, search parameters for searching the optical disk 9 are stored in the original parameter file 1. Next, the binary search processing unit 2 searches the directory 3 that serves as a database, obtains the optical disk name and the optical disk address from this directory 3, and sets them in the search parameters. After that, the parameters are classified by the optical disk name, and the search parameters are divided into the first parameter file 4 and the second optical disk where the search program reads the different optical disks.
Divide into the parameter file 5. In this embodiment, the search parameters are classified into the parameters of the optical disc 9a and the parameters of the optical disc 9b.

The first extraction processing section 10 searches the optical disk 9a set in the parameter of the parameter file 4, extracts the data obtained by this search, and outputs it to the first extracted data file 6.

Similarly, the second extraction processing section 11 searches the optical disk 9b set in the parameters of the second parameter file 5 to extract data, and outputs this data to the second extracted data file 7.

After these two extraction processes are completed,
The merge processing unit 12 operates. The merge processing unit 12 performs a process of integrating the first extracted data file 6 and the second extracted data file 7, and the data integrated by this process is output to the third extracted data file 8.

In this case, a parameter file, an extraction processing section, and an extraction data file are required for each.

As described above, according to the present invention, when searching for optical disks, unlike the conventional method of sequentially reading and searching for a plurality of optical disks with one program, a plurality of optical disks are searched. The search time can be shortened because a plurality of programs are simultaneously processed by using a plurality of drive devices for the optical disc autochanger.
