Abstract
An information processing apparatus for recording and/or reproducing information on and/or from a recording medium using a plurality of probes includes a plurality of probes and a substrate for supporting the plurality of probes. A first electrode is provided on the substrate and a second substrate is provided on the recording medium. An electrostatic capacitance between the first and second electrodes is detected so that an interval between the substrate and the recording medium is adjusted on the basis of the detection result. One of the first and second electrodes has a plurality of electrodes end faces with different heights.
