    • The apparatus comprising:

      a plurality of probe electrodes (31) for recording and reproducing information;
      support means (33) for unitedly supporting said plurality of probe electrodes (31) in parallel facing the medium (34);
      adjusting means (35,37) for adjusting a spacing between said medium (34) and said support means (33);
      displacing means (32) for, in order to independently adjust a spacing between said medium (34) and each tip (3101) of the probe electrodes (31), independently displacing the respective probe electrodes (31) in a direction of the spacing; and
      control means (39,310) for controlling said displacing means (32) such that all spacings between said medium (34) and said respective probe electrode tips (3101) are made equivalent;
      in which apparatus or method said control means (39,310) are adapted to control said adjusting means (35,37) such that, upon the control of said displacing means (32), an average of displacement amounts of said plural probe electrodes (31) is substantially zero or a sum of squares of displacement of said plural probe electrodes (31) is minimized.
