Abstract:
This object aims to propose an optical information recording medium configured to make copyright protection possible, an information recording method for an optical information recording medium and a recording device. An optical information recording medium is proposed to have a recording area available for recording data by laser light, wherein the recording area is provided with a user data area and a management area. The management area written in the optical information recording medium includes a recording format management area provided with information for carrying out operations that identify a format recorded in the user data area, convert the format into a predetermined signal system in accordance with an identified result and record the converted format; a recording condition management area provided with information to make the control of recording conditions of the laser light feasible when the data are recorded at the user recording area; and an authentication identification area provided with information for carrying out an operation that identifies whether or not the optical information recording medium is authenticated by a third party.
