PROBLEM TO BE SOLVED: To write address information/ID information in a magnetic disk in which a recording track is formed into a land shape. SOLUTION: The information writing device is constructed so that one sector is constituted of a projected data area, a unique area, a clock area, a servo area, and an address information/ID information area, a plurality of annular recording tracks containing a plurality of sectors are formed from a center hole toward an outer peripheral side, and address information/ID information is written in a magnetic disk having a recording track magnetized. This device is provided with a detection part for detecting the unique area, a reading part for reading a control signal written in the clock area, an information generation part for generating unique address information/ID information, and a writing part for writing the unique address information/ID information generated by the information generation part in the address information/ID information area belonging to the same sector of the unique area based on the control signal read by the reading part when the unique area is detected by the detection part.
