Reading Dynamics in Magnetic Super Resolution Media

Abstract

Reading dynamics in front aperture detection (FAD) and center aperture detection (CAD) magnetic super resolution (MSR) media is studied using a high speed Kerr microscope system with 10-ns resolution, The effects of disk structure and reading conditions on the reading dynamics are investigated, Readout of 0.2 micron domains is successfully demonstrated using 488 nm wavelength light on CAD MSR media,
