Information processing apparatus and scanning tunnel microscope |
摘要 |
<p>An information processing apparatus for effecting recording of information on and/or reproduction of information from a recording medium is provided with a probe electrode, a cantilever piezo-electric member, a controller and a detector. The probe electrode is relatively displaced to the recording medium by the cantilever piezo-electric member. The controller applies a control signal to the cantilever piezo-electric member to control the cantilever piezo-electric member. The detector detects a minute signal obtained on the tunnel effect caused between the probe electrode and the recording medium. A switch element is further provided on the apparatus so as to electrically disconnect between the cantilever piezo-electric member and the controller during the minute signal being detected by the detector. <IMAGE></p> |
