Near-field optical recording with a solid immersion lens (SIL) is a promising and logical technology for commercial optical data drives with data storage densities beyond that of Blu-ray Disc. In many aspects the technology of near-field recording with a SIL is very similar to conventional optical recording, however for lenses with a numerical aperture (NA) exceeding unity certain optical effects occur that do not play a role in conventional optical recording systems. An example of one such effect that we found in practice is a polarization induced spurious wave front aberration. In this paper we report on the analysis and correction of those polarization induced spurious wave front aberrations in $\mathrm{NA}>1$ Solid Immersion Lenses and in particular for the $\mathrm{NA}=1.9$ lenses used in our experimental near-field optical recorder.
