Research Abstract

A novel data storage media using spatially pattered nanoparticles with buffer ring was fabricated for high dense digital data recording. Polarization interferometric nonlinear-optical confocal microsope was developted for digital data reconstruction. Increasing the contrast transfer function (CTF) of the microscope proposed, the system can use much smaller nanoparticles as storage data pits.
