Abstract

Recording characteristics of (Dy,Tb)FeCo disks were studied. `Anisotropy dispersion´ of rare earth constituents such as Gd, Tb, and Dy qualitatively accounts for domain wall mobility and domain size. Results, obtained in this study, indicated that both coercivity and domain wall mobility play critical roles in the magnetooptical recording
