DEFINITION

Classification: 365/1

MAGNETIC BUBBLES:

(under the class definition) Subject matter where the information stored in a magnetic medium is a domain bubble (a single walled magnetic domain having an outer boundary which closes on itself and has a geometry independent of the boundary of the sheet in which it moves, usually in the form of a cylinder).
