Recording medium, recording method, and readout method.
摘要
<p>A recording medium comprises an electroconductive oxide film held between a substrate and an insulating oxide film. A recording method comprises applying locally a voltage onto the medium to form a portion different in electric resistance or oxygen content in the electroconductive oxide film. A record-readout method comprises applying a voltage to the electroconductive oxide film and having information recorded thereon, detecting the intensity of current flowing through a recorded portion to read out the recorded information.</p>
