摘要： An information recording/reproducing device according to an example of the present invention includes first and second heads, a recording medium having a data area from which recording data is read by the first head and a servo burst area from which a servo burst signal is read by the second head, a driver which performs positioning of the second head based on the servo burst signal, and a resistor which covers a surface of the servo burst area and does not cover a surface of the data area. The recording data and the servo burst signal are recorded by a pulse signal.
