Reported is an investigation into the effect of spherical aberration caused by the mismatch of the refractive indices between the recording material and its immersion medium on the three-dimensional optical data-storage density in a two-photon bleaching polymer. It is found both theoretically and experimentally that spherical aberration can be compensated for by a change in the tube length at which a microscope objective is operated in recording and reading processes. After compensation for the spherical aberration it is possible to achieve a three-dimensional recording density of 3.5 Tbits/cm3 for a commercial objective with a numerical aperture of 1.4.
