Recording medium, recording method, and readout method |
摘要 |
A recording medium comprises an electroconductive oxide film held between a substrate and an insulating oxide film. A recording method locally applies 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 the steps of applying a voltage to the electroconductive oxide film having information recorded thereon, and detecting the intensity of current flowing through a recorded portion to read out the recorded information.
