Abstract
To perform a binder through retrieval on binders which are set out on an optical disk and have different title structures, those binders containing the same key attribute data as a designated retrieval key are retrieved. When binders to be linked are selected from the retrieved binders, only those keys containing the same attribute data as the designated key are extracted from the selected binders. The extracted keys are sequentially arranged in the extracted order, thereby creating a title table for a link binder on a magnetic disk. This title table is retrieved to provide desired image imformation. Alternatively, a binder number/key correlation table is created on the magnetic disk, in accordance with the selection of the binders to be linked. This binder number/key correlation table includes the quantity of linked binders, the number of retrieval keys, the number of each binder and information relating to linked keys for each one of the linked binders. The title table of a binder associated with the designated key or keys, which is indicated by the binder number/key correlation table, is retrieved to provide the desired image information.
