PURPOSE:To prevent the degradation of transfer margin in a boundary part, by setting the angle, which is formed by the transfer direction of magnetic bubbles and an ion implantation region boundary line in the connection part between an ion implantation magnetic bubble transfer path and a soft magnetic material transfer path, as prescribed. CONSTITUTION:In the connection part between a magnetic bubble transfer path 23 and a transfer path 24 consisting of ''Permalloy '' or the like in an ion implantation region 21, and angle theta which is formed by the transfer direction of magnetic bubbles to the trasfer path 24 and the boundary line between the region 21 and other regions is set to <=90 deg.. Thus, the margin of the bias magnetic field dependent upon the angle theta is changed, and the degradation of the transfer margin of magnetic bubbles in the transfer path boundary part is prevented. |
