Abstract: A magnetic bubble shift register store having a plate of magnetic material whose preferred magnetization direction extends transverse to the plane of the plate and in which bubbles are situated, said plate having two separate, elongated generally parallel extending continuous bubble paths, of lower bubble energy in comparison with the vicinity; the center lines of said paths being situated at a distance from each other which is at least equal to the mean bubble diameter. The 0-bits of written information to be transported and stored are represented by bubbles in the one path, while the 1-bits thereof are represented by bubbles in the other path. The interaction between the bubbles ensures that bubbles in the two paths cannot pass each other, with the result that the information represented by the bubbles can be unambiguously transported and maintained in the path direction.

Abstract: There is disclosed an apparatus and method for constructing integrated buffered devices for use with magnetic bubble domain memories. A small storage loop acts as the buffer memory and is interfaced with the main storage loops through a new circuit component. The new circuit component performs the function of transferring a bubble from one track, holds the bubble for a prescribed number of cycles, and then transfers the bubble to another track. Thus, any arbitrarily located bubble within the storage loop can be transferred to any arbitrary location in the buffer loop.

Abstract: A major/minor loop bubble memory configuration that provides gap free serial access to the data in the minor loops and which maintains the non-volatility of data when subjected to a power-on-off-on sequence. The configuration includes a timing minor loop in combination with the data storage minor loops in the major/minor loop array. The placement of a single timing bubble within the timing loop permits gap free serial access to the data in the remaining storage minor loops.

Abstract: A random access bubble memory directs a plurality of continuous streams of bubbles toward a plurality of storage loops. A write decoder selects one continuous stream of bubbles. An annihilator then transforms this one continuous stream of bubbles into the desired data pattern which is then stored in a selected loop. While the data pattern is being formed, a read decoder directs the data which had been stored in the selected loop to a bubble detector. This memory has a unified read/write cycle which permits intermixed read and write, read/modify/write, and swap operations. This bubble memory allows a user to remove power abruptly during a read/write cycle without returning a partially processed block to its storage loop and without saving the identity of the block. In a preferred embodiment, the read and write decoders are operated simultaneously by identical control currents.

Abstract: Circuitry for use in bubble memory propagation wherein field drive coils receive energy from an energy storage device (capacitor) through a plurality of selectively located and timed switches. A basic digitally controlled switching arrangement is illustrated in matrix form and, in one embodiment, one capacitor with two voltage sources and, in another embodiment, two capacitors and a single voltage source are utilized. Selective timing of the opening and closing of the switches provides a digitally controlled series of 1/2 sine wave current pulses to meet operating requirements for bubble propagation. Additional variations of the selective timing of switch opening and closings are used to elongate the start and stop pulses to provide better operating margins for these events. Field rotation in either clockwise, or counter-clockwise, or a mix of rotational senses is readily achieved under digital control.

Abstract: Magnetic bubble domains are propagated in a magnetic medium in a desired direction using magnetic fields which have no spatial gradients. This is in contrast with conventional propagation techniques where magnetic overlays have to be used with applied magnetic fields in order to move domains. Depending upon the wall magnetization configurations in the domains, these domains are propagated by using, for example, a combination of a steady magnetic field and a magnetic field which varies with time, such as a pulse field or a sinusoidal field. This type of propagation is termed automotion. Bubbles which can automote are generated and detected in the magnetic medium using the principles of automotion. Embodiments are shown for representation of information using different types of bubbles, and in particular it is shown how to discriminate among bubble domains having wall configurations having a common winding number s. In a particular embodiment, a modulated bias field is superimposed on a steady magnetic field in the plane of the magnetic medium. Depending upon the direction of the in-plane magnetic field and upon the wall magnetization configuration of the bubbles, the bubbles can be made to move in different directions regardless of the directions of the modulated bias field.

Abstract: An output timing arrangement for single-wall magnetic domain apparatus for ensuring the concurrence of a domain-generated output signal and the output strobe. Voltages generated at the detector array of the apparatus by its in-plane rotating drive field are employed prior to readout to control the timing of the strobe signal. More specifically, the voltages generated by the rotating field at the second harmonic frequency of its fundamental frequency are filtered out to generate timing data indicative of the precise time at which a domain-generated signal may be expected during a subsequent readout operation. The occurrence of the output strobe signal is thus caused to track variations in the phase angle of the rotating field, which variations in the past frequently affected the strobe timing and hence the reliability of readout.
