Abstract :
We have previously proposed LIMDOW-MO (laser intensity modulation direct overwrite magneto-optical) disks with MSR (magnetically induced super resolution) by FAD (front aperture detection) system. In this study, we improve recording characteristics of LIMDOW-MSR disks using RAD (rear aperture detection) without any initializing magnet for the MSR layer. This enables high density recording as a result of low crosstalk.
