Energy storage in a transformer core is an undesired parasitic element. With a high permeability core material, energy storage is minimal. In an inductor, the core provides the flux linkage path between the circuit winding and a non-magnetic gap, physically in series with the core. Virtually all of the energy is stored in the gap.

Book Title Magnetic. Drawing inspiration from general circuit theory and magnetic bubble technology, here we demonstrate a class of integrated circuits for executing Cited by: This chapter provides an overview of magnetic information storage systems, particularly magnetic hard disk drives and reviews basic magnetics.
Among the magnetic storage systems, the magnetic hard disk drive is the dominant secondary mass storage device for computers ranging from notebooks to mainframes because of its large storage capacity, low cost per megabyte, reasonably fast access time and a relatively mature manufacturing infrastructure.
Another recent development in mass storage technology is the introduction of magnetic bubble devices. Due to its high density, low cost and nonvolatility, magnetic bubble memory is expected to replace a majority of applications where conventional devices (such as disks and tapes) are used.
Of course it can be used to simulate magnetic disks, so that the change to the existing software as Cited by: Glossary. Magnetic Bubble Memories.
Magnetic bubble memories use small magnetized areas, called bubbles to represent data bits. An alternating electric field causes the bubbles to shift down the register.
A constant magnetic field must also be supplied by an external magnet. Such synchronous logic is now shown for a system of ferrofluid droplets, with a rotating magnetic field providing the computer clock rate.
Magnetic Bubble Technology: Integrated-Circuit Cited by: To make the bubble bigger, Gallagher and his colleagues blew up the magnetic field -- much like inflating a balloon -- by injecting ionized gas near the coil.
The innovative use of ionized gas (called plasma) to blow up the magnetic bubble is what gives the project its name: Mini-Magnetospheric Plasma Propulsion or M2P2 for short. BOBECK and H.

Abstract. This is a review of the most successful technique for the growth of garnet films for bubble memory applications. Subjects discussed include background, chemistry of the rare earth iron garnets and flux systems, equipment and procedures commonly used for liquid phase epitaxial crystal growth, and growth by: 6.
We demonstrate universal computation in an all-fluidic two-phase microfluidic system. Nonlinearity is introduced into an otherwise linear, reversible, low–Reynolds number flow via bubble-to-bubble hydrodynamic interactions.
A bubble traveling in a channel represents a bit, providing us with the capability to simultaneously transport materials and perform logical control by: For contributions to integrated circuit interconnects and integrated inductor technology.

Bubble memory was a weird technology, it was a kind of magnetic integrated circuit. A ferrimagnetic substrate was made from artificial garnet.
Specially-shaped electrodes were deposited on the surface, and the whole thing was wrapped in two coils at right angles and sandwiched between two permanent magnets.

Spiller, "Soft X-Ray OpticsA Personal History," Proc. SPIE(). Google ScholarCited by: Early magnetic storage devices were designed to record analog audio signals. Modern magnetic storage devices are designed for recording digital data. In early computers, magnetic storage was also used for primary storage in a form of magnetic drum, or core memory, core rope memory, thin film memory, twistor memory or bubble memory.Bubble memory is a type of non-volatile computer memory that uses a thin film of a magnetic material to hold small magnetized areas, known as bubbles or domains, each storing one bit of data.
The material is arranged to form a series of parallel tracks that the bubbles can move along under the action of an external magnetic field.
