    摘要: An optical recording medium, wherein a recording layer is formed on a substrate to which a light beam is applied to record, erase, and read data with said recording and erasing of data being carried out by means of phase changes between amorphous and crystalline, and which recording medium has a laminated structure made up of a transparent substrate on which at least a first dielectric layer, recording layer, second dielectric layer, and reflecting layer are formed in this order; and the second dielectric layer not being transparent. Said optical recording media permit low-power recording and erasing, remain stable after repeated recording and erasing, and hardly suffer deterioration in performance or formation of defects. They are high in resistance to moist heat and oxidation and long in service life.
