Abstract
Very small domains are recorded on the MAMMOS disk and they can be detected
using RF readout field. The MO signal amplitude of 20 nm domains ran be en
hanced to the saturated signal level. For these small domains, the thermal
stability problem is investigated, Even if high laser power for readout is
irradiated to the small domains, the reproduced sihnal was maintained. The
result indicates that the recording layer of TbFeCo possesses an advantage
for para-magnetic limit problem over 100 Gbits/in(2).
