A recording medium is prepared by irradiating an electron beam on a substrate following a certain pattern, then vapor depositing a metal onto the substrate to form a track comprising ultra-fine particles of the metal, further providing a metal layer on the substrate, and providing a recording layer on the metal layer. Recording is effected on a track having a preferable width of 40 .ANG. to 400 .ANG. formed on the recording surface of the medium by applying a pulse voltage or current between the medium and a probe arranged approximate thereto.
