Abstract

PURPOSE:To quickly execute read of discriminating information and retrieval by extracting the discriminating information recorded in at least other disk and recording it in one piece of plural disks. CONSTITUTION:A disk placing part 6 is constituted so that two disk containers (disk stacks) 1, 2 can be attached and detached in the direction as indicated with an arrow A, and in one disk stack 1 (2), one piece of directory information exclusive optical disk D0 and N pieces of data optical disks D1-DN are contained. Also, as for the optical disk D0, each directory area 101-10N (each discriminating information stored in one piece of optical disk) of other data optical disks D1-DN stored in one disk stack are extracted, respectively, and recorded in one piece of optical disk. In such a way, read of the discriminating information recorded in the disk, and the retrieval can be executed quickly, and also, even in case a breakdown of directory information stored in a storage part has been generated due to cut-off of a power source and other accident, its release can be executed easily.
