Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an image information storage and retrieval device for storing and retrieving image information such as documents and drawings on an optical disk. Copy at high speed (
9゜Conventional technology regarding methods for copying) In general, image information recording and retrieval devices read image information such as documents and drawings by optical two-dimensional scanning and sequentially store them on an optical disk. There are known devices that record management information such as keywords for searches.

The management information consists of 115 combined (document) eye positions of 1 [Management of multiple image information], and is stored in an area separate from the image information. 111 The JAN to read the image information corresponds to 2 and 11;
Search by inputting the keyword of the management information 5.C.
Playback on an RT display device, printer, etc.

In order to create a copy of an optical disc, at least two optical disc devices that read and record information on the optical disc are installed in an image information recording and retrieval device. In the conventional copying method, first, the management information of one document is read from the optical disk to be copied, and the image information is read based on the address of this management information and stored in the page memory device. Next, the stored image information is stored on the optical disk to be copied, and by repeating this process, all the image information is stored, and finally, all the management information is stored.

Problems to be Solved by the Invention However, according to such a copying method, the area on the optical disc where management information is recorded and the area where image information is recorded are separated, making it difficult for the optical disc device to play/record. There is a problem in that the printing head moves to both areas for each document, and therefore it takes time to copy.

Incidentally, when image information is recorded in a plurality of sectors of an optical disc, if there is a defective sector on the recording medium of the optical disc, the defective sector is recorded with a hard disk.

Therefore, the start address and end address of image information depend on the recording medium, and it is impossible to copy information on an optical disk in units of physical addresses (usually called tracks or sectors, as with magnetic disks).

Therefore, at present, copies of optical discs are read out in units of one document and stored in units of one document.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a copying method for an image information storage and retrieval device that can shorten the time required to copy an optical disc by shortening the moving distance of the playback/recording header of the optical disc device. shall be.

Furthermore, all the address information of the image information stored on the second optical disk is read and stored in the respective storage devices, and finally, all the management information of the optical disk @1 is read and the address information is stored on the second optical disk. The address information is converted into address information and stored on the second optical disk.

Effects of the Invention With the above-described configuration, the present invention shortens the copying time by shortening the moving distance of the header that reads and stores all the management information and all the image information at once.
