UNIFORM ROTATING FIELD NETWORK STRUCTURE TO EFFICIENTLYPACKAGE A MAGNETIC BUBBLE DOMAIN MEMORYABSTRACT OF THE INVENTIONA unique and compact open coil rotating magnetic fieldnetwork structure to efficiently package an array of bubble domain devicesis disclosed. The field network has a configuration which effectivelyenables selected bubble domain devices from the array to bedriven in a vertical magnetic field and in an independent and uniformhorizontal rotating magnetic field. The field network is suitablyadapted to minimize undesirable inductance effects, improve capabilitiesof heat dissipation, and facilitate repair or replacement of a bubbledevice.The invention described herein was made in the performance ofwork under NASA Contract No. NAS1-12435 and is subject to the provisionsof section 305 of the National Aeronautics and Space Act of 1958(72 Stat. 435; 42 U.S.C. 2457).
