    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.

    Abstract: Layers of materials in which single wall domains can be moved and operated in the familiar field access mode are organized in an array and operated in a word-organized block access fashion which permits an advantageous noise cancellation detection arrangement.

    Abstract: A single wall domain arrangement comprises channels which are defined in a layer of magnetic material by patterns of magnetically soft elements along which domains move responsive to a magnetic field reorienting in the plane of the layer. The elements are formed by a single photoresist process resulting in the simultaneous formation of a compatible magnetoresistance detector.

    Abstract: Single wall domains moved in a slice of a host magnetic material, by changing magnetic pole patterns exhibited by a pattern of magnetic elements in response to a magnetic field reorienting in the plane of the slice, are expanded during propagation at a prescribed point in the pattern due to a localized modification in the pattern there. The expansion of domains relieves constraints on turns in the channel as well as detector design.

    Abstract: Magnetic crystals have been found capable of structuring themselves into information channels under certain magnetic conditions. A propagation mechanism for moving magnetic domains, such as bubbles, along channels so defined has been discovered also. The dimensions of the channel and the size of the bubbles movable along the channel depend on material properties rather than on photolithographic resolution. Thus, the necessity for photolithographic processing previously employed for defining the familiar bubble movement implementations is eliminated, and both packing densities and yields are expected to be extremely high.
