摘要：PROBLEM TO BE SOLVED: To enhance reliability in recording and to rapidly record without damaging a recording medium by connecting one end of a piezo-resistor to an external circuit through a current limiting resistor formed in the vicinity of a thin film cantilever on a support member and making the current limiting resistance a variable resistor. SOLUTION: By forming the current limiting resistor 105 in the vicinity of the thin film cantilever 101 on the support member 104, the reliability of recording is improved. Further, by making the current limiting resistor 105 a variable resistor, the value of the current limiting resistor 105 is reduced when piezo-resistance is measured with an AFM(atomic force microscope), and the whole resistance of a piezo- resistance detection circuit is reduced, and the piezo-resistance is measured with an AFM sensitivity. Further, the resistance value of the current limiting resistor 105 at recording is controlled to an optimum value corresponding to every recording medium and according to the type and the film of the recording medium, and stable information recording is performed regardless of the film thickness and the type of the recording medium.
