PURPOSE:To provide a number of recording layers varying in type in a recording system by phase sepn. CONSTITUTION:The reloadable recording layer is constituted by selecting the compsn. positioned near the spinodal line in the phase diagram of a phase separating material or the inner side thereof as the compsn. of the recording material. The recording layer of DRAW type by spinodal decomposition is constituted by selecting the compsn. existing on the inner side of the spinodal line in the phase diagram of the phase separating material as the compsn. of the recording material. Further, the recording layer of DRAW type by the phase decomposition by nucleation and its growth is constituted by selecting the compsn. existing between the binodal line and spinodal line in the phase diagram of the phase separating material as the compsn. of the recording material. The optical recording medium is thus obtd. |
