ABSTRACT:
A recording-reproducing apparatus comprises a recording medium provided with a recording layer containing at least two kinds of compounds, which compounds respectively form phases, and having regular periodic structure comprising said phases as constituent units; a probe electrode disposed opposingly to said recording medium; a circuit for applying a voltage between said recording medium and probe electrode; and a circuit for detecting an electric current flowing between said recording medium and probe electrode. A recording-reproducing method comprises detecting by the use of a probe electrode, at least one phase on a recording medium of the apparatus and recording information or reproducing the recorded information at the position where said phase has been detected.
