PURPOSE:To improve recording density and reproducibility, etc., by physically sectioning an area, where electric charges are accumulated, and limiting the spread of the electric charge at the time of recording or accumulating. CONSTITUTION:With a glass substrate 8 as a supporting body, a recording medium is formed with the structure of a metallic lower electrode 9, monomolecular accumulating film 10 and metallic upper fine electrode 11. Then, the monomolecular accumulating film 10 is operated as an insulation film and the upper fine electrode 11 is operated as the electric charge accumulating area. Namely, as recording operation, by getting an probe electrode 5 of an STM close to the upper fine electrode 11 on the recording medium and further impressing a voltage between the probe electrode and the lower electrode, the electric charge is injected. In such a way, since the area accumulating the electric charges is physically sectioned, the spread of the electric charge is limited or controlled. Thus, the recording density is improved and the reproducibility of recording and reproducing is improved. |
