For the area to be verified, the user selects one or a plurality of lead-in, inner, middle, and outer areas. For the verification mode, the user selects one of an immediate execution mode and an in-close-command execution mode. In a duplicator or the like in which same data is recorded on a plurality of optical disks, the user can designate an important data portion and selectively execute verification.
