ABSTRACT:
In an apparatus including a recording medium on which a multiplicity of information bit lines are formed and a probe facing the recording medium, the displacement between the center of the information bit line and the locus of the probe is detected at the time of relatively moving the probe along the information bit line. Tracking is performed in such a manner that the probe scans the center of the information bit line in accordance with the detection results.
