An electrode substrate and a recording medium having a smooth surface with surface unevenness of 1 nm or less and a size of 1 .mu.m.quadrature. or more are disclosed. An electrode substrate and a recording medium having a concave-shaped groove for tracking on the surface, which groove has a depth which can detect of the tunnel current from the bottom thereof by a probe electrode for scanning the surface are also disclosed. Information processing devices equipped with the smooth recording medium, an electroconductive probe arranged approximate to the recording medium and a pulse voltage application circuit for recording are also disclosed.
