Abstract: Single wall domains are moved generally in a slice of magnetic material by a magnetically soft T and bar-shaped overlay pattern on a single surface of the slice in response to a magnetic field rotating in the plane of the slice. The overlay pattern includes consecutive elements alternatively parallel to first then second orthogonal axes. Operational and manufacturing advantages are realized if overlay elements aligned with one axis are on one surface of the slice and the overlay elements aligned with the orthogonal axis are on the other, the relative positions of all elements with respect to one another in the plane of the slice being preserved otherwise.

Abstract: A low power magnetic bubble memory for use in, for example, telephone repertory dialer operation is achieved with existing bubble functional elements. An electrical conductor pattern is adapted to input, simultaneously, bubble patterns representative of decimal digit information as well as the control information for properly queuing and storing that information. An adaptation of the familiar major-minor bubble organization is employed. The dialer is designed to operate on sufficiently low power to be powered entirely from a telephone central office.
