Abstract

PURPOSE: To improve the controllability, by writing previously the index information into a floppy disk and giving an access the floppy disk based on the positioning information of the floppy disk.
CONSTITUTION: The information necessary for the access procedure such as the type of the floppy disk and others is written previously into the floppy disk. This information is read by all means for all floppy disks stored in a magazine and before starting the data process. A correspondence is secured between the floppy disk and its storing address, and the address of the floppy disk to which an access is to be given is selected by the program of an information processor based on said correspondence. In other words, the operator has not to consider the order by which the floppy disk is put into the magazine 4, thus improving greatly the controllability.
