Abstract

A recording medium includes a substrate electrode, a recording layer constituted of a monomolecular film of an organic compound or a built-up film thereof, and a photoconductive thin film, laminated in this order on a substrate. The photoconductive thin film may preferably be divided to a plurality of isolated sectors. The recording medium is used in an ultra high density information processing apparatus with a probe electrode disposed close to the medium, a power source for applying a voltage between the medium and the probe electrode, and a light source for irradiating the medium.
