Abstract
A typical head-lens configuration for near-field recording consists of an objective lens followed by a solid immersion lens (SIL) as shown in Fig. la. The SIL is a hemispherical lens element and its purpose is to produce a focal spot which is smaller than that produced by the objective lens alone.
