Recording and reproducing method of optical recording medium
专利汇可以提供Recording and reproducing method of optical recording medium专利检索，专利查询，专利分析的服务。并且PURPOSE: To carry out high-density recording with high sensitivity by irradiating light on an optical recording medium using a thin film wherein fine particles showing a metal-insulator transition are dispersed as the recording film, and utilizing the change in the optical characteristic at that time.
CONSTITUTION: Mass movement of electrons of fine particle is caused, when light is irradiated on a film wherein the fine particles are dispersed in a medium. Consequently, plasma resonance absorption is produced, and the light absorption results. The absorption wavelength and absorption coefficient of the light absorption depend on the property of the medium, the space occupation ratio of the fine particles, the diameter of the fine particle, the concn. of free electrons, the effective mass, etc. Accordingly, the film contg. fine particles is fixed to a substrate, light is irradiated on the film to generate a metal-insulator transition at the irradiated site by the heating effect, the absorption wavelength and absorption coefficient of the plasma resonance absorption are changed to record a signal, the light of wavelength of the plasma resonance absorption is transmitted to read the presence and absence of the light absorption, and the reproduction of the recorded information is carried out.
