摘要： Magnetic bubble domain memory circuit in which magnetizable overlay patterns of magnetically soft material, e.g. permalloy, are provided as bubble propagation elements on a bubble-supporting magnetic layer to define major and minor bubble propagation paths. The bubble propagation elements are arranged to form major propagation paths defining a bubble input section and a bubble output section respectively. A plurality of minor propagation paths in the form of closed storage loops defining a bubble storage section are disposed between the input and output bubble sections, being arranged in even and odd blocks of minor propagation paths. Input swap transfer gates and output replicate gates are provided between the bubble storage loops and the input and output sections respectively. The input swap transfer gates and the output replicate gates are of double level construction, each type of gate including a hairpin element at the first level and a 90.degree. hook-like element at the second level which is correlated into bubble propagation elements included in a minor storage loop. The 90.degree. hook-like elements of corresponding swap transfer and replicate gates are respectively situated at the input and output ends of the minor storage loops, forming the opposite bights of the loop. Bubble generators and detectors are associated with the input and output bubble sections respectively at the opposite ends of the minor storage loops to provide a magnetic bubble domain memory chip for data processing purposes. Data as represented by the presence or absence of a magnetic bubble is transferred into the minor storage loops and replicated outwardly therefrom into the bubble output section for detection in a manner enabling such data to be received by the bubble detector for readout at the field rate.

摘要： Magnetic memories and methods are disclosed. A magnetic memory as described herein includes a plurality of stacked data storage layers to form a three-dimensional magnetic memory. Bits may be written to a data storage layer in the form of magnetic domains. The bits can then be transferred between the stacked data storage layers by heating a neighboring data storage layer, which allows the magnetic fields from the magnetic domains to imprint the magnetic domains in the neighboring data storage layer. By imprinting the magnetic domains into the neighboring data storage layer, the bits are copied from one data storage layer to another.

摘要： A continuous-media or patterned-media disk drive with a low ratio of linear bit density in bits per inch (BPI) in the along-the-track direction to track density in tracks per inch (TPI) in the cross-track direction has a magnetoresistive read head with high cross-track spatial resolution. The read head is located between two magnetic shields, with the shields and read head formed on a side surface of the head carrier perpendicular to the carrier's disk-facing surface. The carrier is supported by the disk drive actuator with the side surface of the carrier oriented generally parallel to the data tracks. In this arrangement the high-spatial-resolution direction of the read head (the transverse direction perpendicular to the side surface on which the head is formed) is in the radial or cross-track direction.

摘要： A magnetic head including a media heating device. Following the fabrication of the heating device, a sacrificial layer of material is deposited to protect the heating device during subsequent process steps. Thereafter, write head components, such as write head induction coils and/or a P1 pole pedestal are fabricated above the heating device, and the sacrificial layer is substantially consumed in protecting the heating device during the aggressive etching and milling steps used to create those components. Further components, including a second magnetic pole are thereafter fabricated to complete the fabrication of the write head portion of the magnetic head. The sacrificial layer may be comprised of alumina, or a material such as NiFe that can act as a seed layer for a subsequent head components such as the P1 pole pedestal.

摘要： A motor based on the wobble motor provides pure rotary motion and can be used as a spindle motor for very small disk drives. The primary components of the motor are fabricated using thin film processes. The rotor has inner and outer rings that are interconnected by flexible members, such as semicircularly-shaped spring elements, with the rings and flexible members being formed of the same material. The rotor resides within the wobble motor stator elements that are circumferentially spaced on a substrate. The inner rotor ring is supported by a bearing structure that may be a ball bearing assembly or a pin bearing comprising a post and a restraining cap. The outer rotor ring functions as the wobble motor rotor and rolls around the inside of the stator as the stator elements are sequentially electrostatically activated. The flexible members act as a transmission to convert the wobble motion of the outer rotor ring to pure rotary motion of the inner rotor ring. The motor can function as a disk drive spindle motor by attachment of a data recording disk to the inner rotor ring and use of appropriate control circuitry to drive the motor at constant speed. The disk drive actuator may be attached to the same substrate that supports the stator elements. The stator elements, the rotor, and the bearing assembly may all be fabricated on a suitable substrate using thin film processes, without the necessity of assembly of separate components.

摘要： An integral combination magnetic transducer and suspension assembly suitable for use in both contact recording and in winchester-type applications is described. A generally rectangular elongate flat suspension member includes a ring-type inductive read/write transducer formed integrally with the suspension member and is embedded in one end of the suspension member. The ring-type inductive transducer is suitable for horizontal recording applications. The transducer magnetic poletips and magnetic gap are formed and positioned such that the poletips and gap are essentially co-planar with the air bearing surface of a slider-shaped protrusion extending from the lower surface of the end of the suspension member adjacent a moving media during operation. The air bearing surface presented to the disk has most of its area covered with a wear layer to minimize wear of the slider surface and poletips.

摘要： A single point bonding tool for use in ultrasonically bonding a fine or ultrafine wire to another electrical conductor, has a thin film resistor integrally formed thereon. The thin film resistor is integrally formed on the bonding tip by standard photolithographic techniques applied to the bonding tool. The tool combines ultrasonic energy and thermal energy provided by the resistor to provide required bonding energy that may be localized both in space and in time. The result offers optimized energy transfer to the selected workpieces and minimizes risk of damage to adjacent, heat sensitive devices.
