Abstract: Disclosed is a method for manufacturing an optical recording medium including an authentication data region and a recording data region. The method comprises: recording at least one intentional error data portion on the authentication data region; and storing an officially certified product determining program that stores authentication information corresponding to the recorded intentional error data in the recording data region. Therefore, the officially certified product determining program determines whether the authentication information and the intentional error data are matched, and only when they are matched is the optical recording medium determined to be an officially certified product, and subsequent program operations are executed.
