Abstract: Amorphous ferrimagnetic layers are described with support stable and mobile magnetic charged walls. These layers can be used as drive layers in magnetic bubble domain devices, and are characterized by very weak even-fold in-plane anisotropy, or substantially zero in-plane anisotropy. The layers are metallic alloy compositions having magnetic properties that can be tailored over wide ranges, and are particularly suitable as drive layers for the propagation of bubble domains of extremely small diameters.

Abstract: A power source device for a bubble memory unit, wherein there is supplied a first DC voltage E.sub.c which is applied to control circuitry for controlling the reading and writing of data, a second DC voltage signal E.sub.d which is applied to drive circuitry for driving a bubble memory element, and a memory signal M.sub.e which enables data to be written in or read from the bubble memory element, the signals E.sub.c, E.sub.d and M.sub.e being made to rise and fall according to a prescribed sequence as a commercial power supply is connected and disconnected. The power source device includes first and second DC power source circuits, a comparator circuit for comparing the magnitude of the first DC voltage E.sub.c with a reference level V.sub.M having a value greater than an allowable lower limit value, and a delay circuit. The second DC power source circuit is actuated following a prescribed time delay which begins when the value of signal E.sub.c surpasses the reference level V.sub.M at the time that the commercial power supply is connected, and the memory enable signal M.sub.e is produced after the second DC power source circuit has been actuated. The memory enable signal M.sub.e is made to vanish when the magnitude of signal E.sub.c drops below the reference potential V.sub.m at the time that the commercial power supply is disconnected, the second DC power source circuit being rendered non-operational following a prescribed time delay.

Abstract: A magnetic bubble memory device according to this invention comprises a plurality of minor loops, a read-out major line is disposed at one end of the minor loops through gates having a replicating function, and a magnetic bubble detector which includes a detecting line is disposed at one end of the major line. Further, a propagation length from the other end of the read-out major line to the detecting line of the magnetic bubble detector is set at a bit length which slightly exceeds four times the number of the minor loops. For this reason, a continuous read-out operation at high speed is permitted without the influence of replicate pulses.

Abstract: A magnetic bubble replication and transfer arrangement is disclosed which provides for replicating magnetic bubbles in thin planar layers of magnetic material without the need for electrical current carrying conductor elements. The arrangement includes a replicating half-disc permalloy element disposed in a particular way between first and second tracks formed from half-disc elements which are deposited on a surface of the magnetic layer. When a rotating magnetic field in the plane of the material is rotated in a predetermined direction with respect to the above arrangement, replication of a bubble in the first track occurs at a replication region where a portion of the replicating element is adjacent the first track. The original bubble continues movement within the first track while the newly formed bubble moves along the replicating element into the second track in response to rotation of the in-plane magnetic field.Transfer of bubbles from the second track to the first track and transfer without replication from the first track to the second track is provided for by applying timed electrical signals to a transfer electrical conductor which is interlinkably disposed between the magnetic layer and elements of the second track and a portion of the replicating element adjacent the first track. The timed electrical signals are applied for specific portions of the rotation cycle of the in-plane field to effect bubble transfer between first and second tracks.

Abstract: A bubble storage system using contiguous propagation elements is described using magnetically soft drive layers for movement of the bubble domains in a bubble domain film, in response to the reorientation of a magnetic drive field in the plane of the drive layers. In contrast with prior art contiguous element propagation structures, charged walls are not employed for movement of bubble domains. Instead, magnetic poles along the drive layers are used to move the domains. Two drive layers are used, each of which is comprised of a magnetically soft material, such as permalloy. The drive layers are located at different heights with respect to the layer in which the magnetic bubble domains exist, the bottom drive layer being comprised of contiguous propagation elements defining a generally undulating edge along which the magnetic bubble domains move. This layer can be comprised of permalloy contiguous disks, diamonds, etc. The top layer is comprised of magnetically soft elements located over the cusp regions formed along the undulating edges of the underlying drive layer. For propagation around the disks or diamonds, the bottom drive layer is predominant in determining bubble motion. However, in the art of the cusp regions along the undulating edge defined by the bottom drive layer, the magnetic poles produced by the top drive layer are predominant. These elements in the top drive layer produce potential wells at those locations corresponding to cusps along the undulating edge defined by the contiguous propagation elements in the bottom drive layer, and therefore control bubble motion in the cusp regions. This eliminates a serious problem to satisfactory bubble motion along contiguous propagation element devices. A single level masking fabrication process is described where the top and bottom drive layers can be fabricated through the same mask, and a total chip design is shown which provides all functions required in a complete storage chip.

Abstract: A gap between sets of contiguous discs defined by unimplanted regions in an otherwise ion-implanted bubble layer allows a merge function to be achieved. The alignment of the gap axis with an axis of symmetry of the bubble layer and the width of the gap are important considerations in the performance of the merge.
