Abstract:
A copy restriction method for imposing a restriction on copying data from a data recording region of an optical recording medium to another medium, where a member removable by a user is attached to the data recording region of the optical recording medium, and the copying is performed by an apparatus which comprises a storage means which stores information indicating a position where the member should be attached on the data recording region, the copy restriction method comprising:a detecting step for detecting a position where the member is attached to the data recording region and outputting information indicating the detected position; a judging step for judging whether the information output in the detecting step and the information stored in the storage means indicate a same position; an instructing step for instructing the user to detach the member from the data recording region when it is judged in the judging step that the information output in the detecting step and the information stored in the storage means indicate the same position; a checking step for checking whether the member is detached after the user is instructed to detach in the instructing step; and an executing step for executing copying of the data from the data recording region of the optical recording medium to the other medium only when it is confirmed in the checking step that the member is detached.
