An optical information recording reproduction device is disclosed which finds the correlation between the ratio of the minimum pit amplitude to the maximum pit amplitude of an RF signal obtained from the light reflected by the pits recorded on an optical disk in a tracking servo mode and spherical aberration in advance, and stores it. In recoding information on the optical disk, the optical information recording reproduction device calculates the ratio of the minimum pit amplitude to the maximum pit amplitude of the RF signal, and compares the calculation to the stored correlation, and feeds back to an aberration correction optical system and a driving mechanical system to correct the aberration into an aplanatic state.
