Paper Abstract

The promise of near-field (NF) optics to increase the density in optical data storage, whether solid immersion lenses (SILs), apertures, or their variants, has not yet been fulfilled, largely because of the difficulties with the head-media interface at near-field dimensions, especially if a design goal is removable media. We introduce a new approach to NF optical storage, in which the near-field elements, in the form of cylindrical NF nano-optics (nOptics), are integral with the media. Combining the advantages of near- and far-field optical data storage, we obtain double the track density of DVD in removable rewritable phase change media. Potential for in-track density increase is also demonstrated. We briefly report on the modeling, manufacture, and performance of NF nOptic media.
