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 superior to that for Ar disk. It seems that high readout stability for Kr disks is caused by the large wall coercivity and the large ratio of wall coercivity to nucleation coercivity.
