Abstract: The magnetic bubble domain memory includes a transfer device for transferring domains from a first register to a second register, or back to the first register. The transfer device includes at least one Y shaped magnetic element, with one transfer path defined by both arms of the Y and the other transfer path defined by one arm and the stem of the Y. A conductor crosses the transfer path along the stem of the Y, with current selectively passed through the the conductor to determine the transfer path. The magnetic element comprises a soft magnetic layer, with the conductor between this and the magnetic support containing the domains.
