To obtain satisfactory spot characteristics to any information recording surface of a multilayered optical recording medium by optimally correcting spherical aberration and third order coma aberration caused by a multilayered structure, shortening of wavelength or heightening of an NA.

When the multilayered optical recording medium is targeted, if CDx(x=1, 2, ...) and CLx(x=1, 2, ...) are defined as a least-squares error value (unit:λrms) of third order coma aberration components generated per unit angle when a substrate of the multilayered optical recording medium is inclined and a least-squares error value (unit:λrms) of the third order coma aberration components generated per unit angle when an object lens is inclined when the prescribed information recording surface x of the multilayered optical recording medium is irradiated with a laser beam, respectively, the third order coma aberration generated by a medium tilt can be corrected by a lens tilt by satisfying a condition; |CLx/CDx|≥1 in each information recording surface x (x=1, 2, ...) of the multilayered optical recording medium.
