Abstract
The low process characteristics of light intensity modulation direct overwrite (LIMDOW) magneto-optical disk with magnetically induced super resolution (MSR) function, especially front aperture detection (FAD) type were investigated. To improve low power margin in FAD-LIMDOW disks, exchange coupling between memory and writing layers should be large on copy temperature. It was confirmed that RE (Rare Earth) -rich composition was suitable for FAD readout and memory layer, and that high recording density LIMDOW disk with wide power margin was obtained.
