Abstract
A magnetic bubble memory of the G-shaped organization is implemented by ion-implantation. Attractive operating margins are realized by the use of transfer-out arrangements which moves bubbles in parallel first to an auxiliary path and thereafter to the major loop in a manner to invert the data.
