An optical information reproducing apparatus for reproducing information by irradiating a recording medium with a reproducing light beam includes a light source for generating the reproducing light beam, a reproducing circuit for reproducing a reproduction signal by using the light beam, and an adjusting circuit for adjusting the light beam power. The adjusting circuit adjusts the beam power to a value larger than the light beam power at which a value obtained by normalizing the reproduction signal with the beam power is maximized.
