Abstract
Recording of multiplexed microholographic gratings with improved recording volume for high density optical data storage is proposed and demonstrated. By using a hybrid diffractive-refractive objective lens with extended depth of focus, we have achieved a recording beam size of approximately 1 μm and a focal depth of 20 μm. Multiple gratings corresponding to spectral lines within the 400-650 μm spectral band have been successfully multiplexed in a single recording spot or pit of size 1.25 μm on a DuPont photopolymer film using a white light source along with narrowband niters or dispersion elements, thus demonstrating the storage of multiple bits in a single pit. Simultaneous readout of multiple bits in a single storage pit is accomplished with a microspectrometer-type readout head using a white light source.
