ABSTRACT:
This is invention provides an information processing system for a disk-like storage medium such as flexible magnetic disks or a DVD-RAMs. The disk-like storage medium stores a first data including at least image data, and a second data for deciding legitimacy of the image data, while a case containing the disk-like storage medium comprises a non-volatile storage device for storing a third data having a predetermined relationship with the second data and storing a fourth data for identifying a location in the disk-like storage medium at which the second data is stored. Whne a predetermined relationship between the second and third data is confirmed, the disk-like storage medium is allowed to be used.
