Abstract

PURPOSE: To facilitate the recording, reproduction and erasion of the signal, by providing the electrode layer, the light absorbing medium layer and the thermoplastic layer successively onto the substrate and then securing a partial absorption and partial reflection of the laser beam projected from outside via the light absorbing medium layer.
CONSTITUTION: The electrode layer composed of the Al, Au and the like is evaporated onto the substrate 1, and then the light absorbing medium layer 8 is formed on the electrode layer to secure a partial absorption and partial reflection of the beam. The light absorbing medium uses the bismuth oxide and other compounds, and the thermoplastic layer 4 is formed on the light absorbing medium. Then the high voltage is applied between the electrode layer 2 and the corona discharging electrode 5 of the information recording medium 9 of such constitution as above, thus ensuring a uniform charging for the layer 4 of the recording medium.
