Apparatus and method for recording and/or reproducing information onto/from a medium through a probe electrode by using a scanning tunnel microscope comprises: a voltage applying circuit to apply a voltage between the medium and the probe electrode, in which the recording operation and/or the reproducing operation of the information onto/from the medium are/is executed by applying the voltage by the voltage applying circuit; a distance adjusting mechanism to adjust a distance between the medium and the probe electrode in a manner such that the voltage applied by the voltage applying circuit and the current flowing between the medium and the probe electrode to which the voltage has been applied by the voltage applying circuit satisfy the current-voltage characteristics such that the current between the medium and the probe electrode also changes in accordance with a change in the applied voltage.

éthode et appareillage servant à enregistrer et à reproduire l'information sur un support ou à partir d'un support au moyen d'une électrode sonde en employant un microscope par effet tunnel comprenant : un circuit de tension servant à appliquer une tension entre le support et l'électrode sonde, dans lequel l'opération d'enregistrement et/ou l'opération de reproduction de l'information sur le support ou à partir de ce dernier sont exécutées au moyen de l'application d'une tension par le circuit de tension; un mécanisme de réglage de la distance destiné à régler la distance entre le support et l'électrode sonde de telle manière que la tension appliquée par le circuit de tension et le courant passant entre le support et l'électrode sonde sur laquelle la tension a été appliquée par le circuit de tension satisfassent aux caractéristiques tension-courant de sorte que le courant entre le support et l'électrode sonde soit modifié en fonction d'une variation de la tension appliquée.
