Abstract
Trilayer optical storage media with lead oxide film as spacer layer showed multiple levels of reflectance change, the reflectance change of each level are high, and write laser power for each level are ranged approximately 1 mw, indicating a potential usage of the media on multiple-valued logic storage. The recording mechanism is primarily due to lead oxide film alone from going through massicot (Pb0), minium (Pb304), complex PbOx , litharge (Pb0), massicot (Pb0) phases and melting by laser heating atdifferent power level. A direct in-contact cover glass is compatible with the recording mechanism.
