Abstract: PROBLEM TO BE SOLVED: To achieve a configuration which can efficiently execute production of a content code file and manufacturing of a disk. SOLUTION: As for production and test of content code including at least either a program or transformation table for applying to the content reproduction, a test for content reproduction is carried out in the same way as a reproducing system of a general user when an information processing system executes signature verification defined in the content code file and succeeds in signature verification. In an initial reproduction test, the content code file in which a test signature is set in a data area different from a normal signature is recorded in an R/RE type disk, and then the test is carried out by recording the content code file in which the normal signature is set into a ROM disk, so that efficient production of the content code and manufacturing of the disk can be achieved.
