ABSTRACT:
An apparatus for reading information from an information medium and/or inputting information to the information medium through a probe electrode includes a voltage application circuit for applying voltage between the probe electrode and the information medium, information reading from the information medium and/or information inputting to the information medium being performed by the voltage application by the voltage application circuit, and a charge removing device to perform a charge removing process for the information medium to which voltage is applied by the voltage application while maintaining the information in the information medium, making it possible to perform highly precise information reading and/or inputting at all times without producing any adverse effects on the information medium due to the charge deposition resulting from the voltage application.
