PURPOSE: An optical recording medium having recorded multi-modulated header signal, a method and a device for recording the header signals, and a method and a device for reproducing the header signals are provided to secure a more wide user data area by increasing recording density. CONSTITUTION: An optical recording medium includes wobble tracks in which user data are recorded, header areas in which header signals loading multi-modulated header information are recorded. A device for recording the head signals includes a multi-modulating part generating the header signals loading multi-modulated header information, a recording part recording the generated header signals. A device for reproducing the header signals includes a reading part reading the head signals, a multi-demodulating part demodulating header information in partial section, a header information synthesizing part synthesizing the demodulated header information for outputting header information.
