Information processing apparatus having face regulating system

摘要

An information processing apparatus is used for recording and/or reproducing information on a recording medium by means of a plurality of probes. The apparatus comprises a substrate carrying thereon a plurality of probes arranged two-dimensionally in a plane, at least three sensors at three different points on the substrate for detecting the distance between the substrate and the recording medium, a switching circuit for selecting a parallel connection or a serial connection for the sensors, and a regulating system for regulating the relative inclination and the distance between the probe plane and the recording medium surface plane according to the output of the sensors connected in series and that of the sensors connected in parallel.
