Abstract
The impact of evanescent coupling on the throughput of the recording process and the resolution of the readout signal in SIL-based systems is presented. The loss of the MO signal due to a wide gap-width may be attributed to the reduction of magneto-optical activity, the rise in reflectance, and the variation of the relative phase between the two components of polarization over the cross-section of the reflected beam. For PC disks, the reduced reflectivity-difference between the crystalline and amorphous states, and the rise in reflectance are responsible for the reduction of readout signal with the increasing gap-width.
