    摘要： An optical disk apparatus using an optical disk in which a layer (a reflectivity adjustment layer) in which the optical constants are changed by melting at the time of irradiation of light is provided separately from a recording layer using a phase change, and the reflectivity at a portion having a high reflectivity on the recording track is 40% or lower at the time of irradiation of strong light, and the reflectivity at the same portion is 60% or higher at the time of irradiation of weak light, wherein when the laser power is set to a power which is higher than the power at which the optical constants of the reflectivity adjustment layer are greatly changed at the time of rewriting and at which a high melting-point component is not melted, remaining of an unerased portion during rewriting due to a difference in reflectivity between the written mark portion and the other portions can be prevented and the possible number of rewritings can be increased, and hence an optical disk which has a high recording sensitivity, can be read by a CD player or others, and can be rewritten by overwriting and an optical disk apparatus using it can be obtained.
