Abstract
Pulse readout technique is viewed as a way to improve the CNR ofreadout signal on super resolution disks, such as Magneto-optical Super Resolution Center Aperture Detection disk (MSR-CAD), Erasable Phase change Super Resolution disk (EPSR), Thermal distribution generated by pulse readout scheme results in more regular shape apertures and narrower wall width on those super resolution disks which leads to better signal quality.
