Near Field Recording Technology

A Laser Beam
B Objective Lens
C Flying Head - Focus controlled by the hard disk-like air bearing, thus eliminating a focus servo system
D Solid Immersion Lens (SIL) - Results in a significantly reduced magnetic bit cell size when compared to conventional technologies
E Plastic Substrate
F Evanescent Coupling - Near field coupling of a laser energy creating sub-wavelength recorded feature size
G First Surface Recording (Top of Substrate) - The hardened magnetic material on the surface of the substrate enables low cost media and high areal densities
H Lens/Substrate Spacing Controlled by Flying Head
I Magnetic Coil - Magnetic coil in the head allows direct overwrite
