PURPOSE:To remove the noise component caused by vibration by impressing a voltage on a recording medium having an electric memory effect from a probe electrode which is driven in a circular motion and performing recording and reproducing. CONSTITUTION:Electric power from a pulse power source 108 is supplied to the probe electrode 102 whose distance with the recording layer 101 of a recording medium 1 is kept constant by a piezo-electric element and whose movement in X, Y and Z directions is controlled by an XY scanning driving circuit 109 and a fine adjustment control mechanism 107 to perform a spiral motion and a counter substrate electrode 103 on the layer 101 opposed to the electrode 102. Thus, the voltage is impressed on the layer 101 having the electric memory effect made of monomolecular film and monomolecular layer built-up film being an organic compound from the electrode 102, and recording and reproducing are performed. Since the probe electrode is so constituted that it does not perform reciprocating motion but the circular motion, the vibration of the probe electrode can be prevented from occurring and the noise component caused by the vibration can be removed. |
