2006 Optical Data Storage Topical Meeting | 2006

A Study of Near Field Recording Optics for Cover-Layer Incident Dual-Layer Disc with an NA=1.45 Hemispherical Solid Immersion Lens

Osamu Koyama; Haruhiko Horiguchi; Chihiro Nagura; Koichiro Nishikawa; Osamu Nagatsuka

Practical optics for a cover-layer incident dual-layer disc with an NA=1.45 hemispherical solid immersion lens are designed, using a spherical aberration compensating liquid crystal cell. A hybrid servo system, gap servo for NA >1 and focus servo for NA < 1, is proposed.
