Estimating the term…
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.
A recording medium comprising a substrate electrode, a recording layer having an electric memory effect provided on said electrode and constituted of a monomolecular film of an organic compound or a built-up film thereof, and a photoconductive thin film laminated on said recording layer, said photoconductive thin film being divided into a plurality of isolated sectors.
An information erasing method for erasing information written in a recording medium comprising a substrate electrode, a recording layer provided thereon and constituted of a monomolecular film of an organic compound or a built-up film thereof, and a photoconductive thin film laminated on said recording layer, said photoconductive thin film being divided into a plurality of isolated sectors, the information being written in a portion of said plurality of sectors, which method comprises a first step of disposing said medium close to a probe electrode and facing toward a light source, a second step of irradiating selectively said portion, and a third step of applying a voltage between said thin film and said probe electrode.
