Abstract
A probe closely positioned to an information carrier in apparatus to effect information reading and/or input on the information carrier is formed by opposing an electrode to an end portion of the probe to be formed. The distance between probe end portion and the electrode is detected to control the position of the electrode with respect to the probe. A voltage is applied to the probe end portion through the electrode under positioning control to form the probe end portion. The probe end portion is formed and may be reformed to maintain reliable performance of the information reading and/or input apparatus.
