Abstract

An information recording and/or reproducing apparatus includes a recording medium having a plurality of segmented planar electrodes, a plurality of probe electrodes respectively facing and electrically connected to the plural planar electrodes, and a circuit for independently applying a voltage for recording and/or reproducing between each pair of the planar electrodes and the probe electrodes. The information recording and/or reproducing apparatus includes a circuit for inputting information to be recorded on the recording medium. A memory other than the recording medium is used for temporarily storing the input information, and a control circuit applies the recording voltages between the plurality of probe electrodes and the segmented planar electrodes in correspondence with the information stored in the memory.
