CONTROL SYSTEM FOR MAGNETIC BUBBLES

A system for controlling magnetic bubbles in a thin magnetic plate comprises a plurality of drive loops disposed in close relationship to the magnetic plate and driven by polyphase drive currents to effect controlled movement of magnetic bubbles contained in the magnetic plate. The drive loops have...

Zusammenfassung:A system for controlling magnetic bubbles in a thin magnetic plate comprises a plurality of drive loops disposed in close relationship to the magnetic plate and driven by polyphase drive currents to effect controlled movement of magnetic bubbles contained in the magnetic plate. The drive loops have a hexagonal shape with six sides so that a magnetic bubble may be accepted by each drive loop along one of three possible directions which are spaced apart at 120 DEG intervals and may be transmitted therefrom along one of another three possible directions which are spaced apart at 120 DEG intervals and which are also spaced 60 DEG from respective ones of the first-mentioned three possible directions.
