We studied a near-field optical recording-flexible optical disk (NFR-FOD) for high-density and high-data transfer rate recording. We prototyped a high-density NFR-FOD that has a track pitch of 0.16 um and we stacked some recording layers on a thin substrate that was 0.1 mm thick. We rotated the NFR-FOD closing the mechanical stabilizer on a drive system with less than 10 ump-p of axial run-out, and performed the precise gap servo at high-rotational speed. We demonstrated near-field optical recording with a solid immersion lens with numerical aperture (NA) of 1.84 on the NFR-FOD. The NFR-FOD has four times recording density corresponding to a capacity of 100 GBytes per layer and a high-data transfer rate of 250 Mbps with rotating at half speed than that of current Blu-ray disc. |
