Abstract

PURPOSE:To increase the tranfer margin, by preventing the introduction of failure of bubble supporting layer in the drive layer, through the Ca, Ge substituted garnet expressed in a given constituent equation as the drive layer. CONSTITUTION:On the magnetic garnet film as the bubble magnetic domain supporting layer, the magnetic garnet film is further provided to form the drive layer. The constituent equation of the drive layer garnet film is expressed as Gd3-x-y-z YbxSmyCa2Fe5-zFe2O12 (where; 1.40<=x<=2.00, 0<=y<=0.50, 0.2<=z<=0.6).As a re sult, the formation of drive layer is made possible without introducing the failue in the bubble supporting layer.
