Design of Elliptic Solid Immersion Lens for Dual Layer Near Field Recording
미디어 내부 2층 근접장 광기록을 위한 타원형상 고체침지렌즈의 설계
Abstract
Near field recording(NFR) technology has been considered as a strong candidate to surpass the far-field diffraction limit imposed by the nature of light in present optical disk drives such as CD, DVD, and BD(Blu-ray Disk). In this paper, we suggest novel inside near-field dual layer recording concept using elliptic shape solid immersion lens(ESIL).
