Abstract
A micro scanning tunneling microscope ("STM") arithmetic circuit device comprises an information-rewritable micro STM recording medium and a micro STM recording apparatus which temporarily stores information on the recording medium such that the information can be read as a variation in a tunnel current. The recording apparatus has a probe (probes) for writing/reading information on the recording medium and a scanner for varying a relationship in position between the probe and the recording medium. The micro STM recording apparatus uses a recording medium having a specific format as the micro STM recording medium in which recorded information is read as a variation in a tunnel current. That is, the recording medium has an address area in which address information is recorded and a data area in which data information is recorded.
