Abstract

An information writing method of an optical recording device selectively irradiates light on an optical recording medium, having a thin organic film containing donor and acceptor molecules, and a pair of electrodes for applying a voltage to the thin organic film, in order to cause charge transfer between the donor and acceptor molecules, and records a change in optical or electric characteristics of the thin organic film by the charge transfer as information. Selective light irradiation is performed while a voltage is applied to the electrodes.
