Pre-formatting for optical recording medium having same-phase wobbling area and different-phase wobbling area

摘要

A method of fabricating an optical recording medium that is adaptive for fabricating a frame wobbling recording medium in which a same-phase wobbling area and a different-phase wobbling area coexist in a track thereof. In the method, a wobbling signal for pre-formatting an identification information for the corresponding area is applied to the first wobbling area. A wobbling signal for pre-formatting an identification information for the first wobbling area positioned at the adjacent tracks is applied to the second wobbling area. A light is irradiated in accordance with a signal in which the two wobbling signals are alternately combined.
