Abstract
An information processing apparatus, which utilizes a physical phenomenon occurring between a probe and a sample to detect information from the sample, includes a device for moving the probe in order to adjust a clearance between the probe and the sample, a device for detecting a physical phenomenon occurring between the probe and the sample, a device for generating a control signal for the moving device to change the clearance between the probe and the sample to a desired clearance, based on a result of detection of the detecting device, and a device for applying an offset signal to the control signal in order that the probe can move with respect to a reference located at a position deviated from a center position of a movable range of the probe by means of the moving device.
