The optical recording medium at least a transparent substrate; a reflection layer; and a print layer. The print layer has a multilayer structure in which a plurality of ink layers made from different inks that have different specific gravities are stacked. A sum of products of viscosity .gamma. (in poise) and weight M (in gram) of the ink used to form the ink layer in the print layer satisfies a relation 30.ltoreq..SIGMA..gamma.iMi (g.multidot.Poise).ltoreq.150.
