A multilayer optical recording medium enabled to retain an ideal signal regenerating property in spite of accidental adhesion of finger mark or alien substance is provided. The multilayer optical recording medium 1 is provided with a plurality of information-recording layers 20, 22, 24, and 26 capable of reading information with a reading light irradiated through a light incidence surface 38A on one side and is so adapted that the light incidence side information-recording layer 26 approximating most closely to the light incidence surface 38A may be set at a small recording capacity as compared with the recording capacities of at least one of the other information-recording layers.
