Abstract
Recording magnetic-field sensitivity and readout stability for Tb/FeCo multilayer magneto-optical (MO) disks, made by sputtering with Kr and Ar gas, were studied. The 100 Oe recording magnetic-field sensitivity for Kr disks was obtained. The readout stability for Kr disk is super ior to that for Ar disk. It seems that high readout stability for Kr d isks is caused by the large wall coercivity and the large ratio of wal l coercivity to nucleation coercivity.
