SCANNING MAGNETIC FORCE MICROSCOPY ON Co/Pt MAGNETO-OPTICAL DISKS
1991
Journal of the Magnetics Society of Japan
Preserved Fulltext
The key advantage of scanning magnetic force microscopy compared to electron microscopy techniques is that regular MO disks can be investigated. This enables one to relate the writing conditions and carrier and noise levels of the read-out signal directly to the magnetic microstructure of the domains on the disk. High resolution images are shown of domains on Co/Pt multilayer MO disks. Marks were written with both laser and magnetic field modulation and tracks were erased under different
