Abstract
Tri-layer magnetic super resolution (MSR) media was designed and fabricated for use with center aperture detection. Because short wavelength recording will be essential in achieving ultra-high density disks, the media was tested on a blue light (488 nm) magneto-optic spin stand to evaluate its MSR performance. A single layer TbFeCo disk was also prepared as a standard. Since the MSR disk forms an effective read-out aperture smaller than the diffraction limited spot size, it was observed that the tri-layer disk yielded larger carrier-to-noise ratio than the conventional TbFeCo disk for sub-micrometer mark lengths as small as 0.2 micrometers.
