    摘要： An information recording method and information recording apparatus is capable of resolving the trade-off relation between recording density and transmittance, wherein either the reproduction (playback) signal quality or the recording sensitivity is lowered. For this purpose, a voltage is applied by way of ball bearings or slip rings to a specified layer of a medium having multiple layers. The light transmittance of the recording layer is changed by application of this voltage. The tradeoff relationship between recording density and transmittance is eliminated thereby, and the recording density and transmittance levels are both improved, so as to enhance the recording reliability.

    摘要： High-speed and high-density recording of a layer-selected optical disc are enabled with a small number of electrodes. A plurality of recording films that are independently selectable are disposed between a pair of electrodes 3 and 8. The recording films are controlled individually in terms of a threshold of voltage required for coloration and electric characteristics. A desired layer can be selected by changing the voltage applied between the pair of electrodes.
