Abstract

Mutual compensating concept between SIL(Solid Immersion Lens) and OL(Objective Lens) of NFR(Near Field Recording) is proposed, designed and manufactured to achieve a high NA and obtain a wider manufacturing tolerance. Tolerance information is present in article. An effective NA of Advanced SIL is 1.7 and adjustment between OL and SIL is carried out using our interferometer. We measured very clear RF signal using 3-axis actuator at Test bed.
