WebFigure 1. Magnetic bubble domains subject to a small (a.) and large (b.) external magnetic field. Setting it up: The crystal is about 2mm square inside a 4cm diameter 1cm deep sealed container that also holds the electromagnet and polarizers. This container sits on a microscope table with. 40x-100x magnification. WebA magnetic bubble-memory stores data in the form of cylindrically-shaped magnetic domains in a thin film of magnetic material (The axis of the cylinder is perperdicular to surface of the material. The presence of a domain (a bubble) is interpreted as a binary 1, and absence of a domain is [email protected] zero.
WebThe magnetic bubble is separated from its environment by the cylindrical magnetic domain wall. The magnetization in the domain wall rotates through 180 degrees. In a bubble domain memory the presence of a magnetic bubble at a particular place and at a particular point of time represents a digital ‘one’, and its absence represents a ‘zero ... WebThe unique features of magnetic bubble memories are used in designing algorithms for elementary file processing operations such as sorting and merging and for basic relational algebraic operations.
