ABSTRACT:
An information recording/reproducing method and apparatus is for carrying out at least one of recording and reproducing information through a probe electrode or through a plurality of probe electrodes on an information recording medium. A probe electrode is disposed on an elastic member. A relative position is so adjusted between the recording medium and the probe electrode that a repulsive force between them is comparative to an elastic force of the elastic member. In case of plural probe electrodes, they are displaced to keep an equal spacing between the recording medium and the respective probe electrodes so that they may have either a zero average or a minimized square sum of displacement. A spacer layer will do for setting a spacing between a probe electrode and the recording medium.
