Towards ultrahigh-density multilayer disk recording by two-photon absorption Conference Paper uri icon

abstract

  • The feasibility of ultra high density multi-layer disk recording by two-photon absorption was analyzed. A photochromic doped polymeric Write Once Read Many (WORM) disk media was used for two-photon recording. A high power short pulse laser beam was tightly focused for recording. The recording occurred only within a small volume around the focus of the laser beam due to two-photon absorption, and hence allowed high density recording. The recording response of the material followed the square of the optical system point spread function (PSF) resulting in a recorded bit size that was 30% less than the Rayleigh criterion PSF.
