UNIFORM ROTATING FIELD NETWORK STRUCTURE TO EFFICIENTLY PACKAGE A MAGNETIC BUBBLE DOMAIN MEMORY ABSTRACT OF THE INVENTION A unique and compact open coil rotating magnetic field network structure to efficiently package an array of bubble domain devices is disclosed. The field network has a configuration which effectively enables selected bubble domain devices from the array to be driven in a vertical magnetic field and in an independent and uniform horizontal rotating magnetic field. The field network is suitably adapted to minimize undesirable inductance effects, improve capabilities of heat dissipation, and facilitate repair or replacement of a bubble device. The invention described herein was made in the performance of work under NASA Contract No. NAS1-12435 and is subject to the provisions of section 305 of the National Aeronautics and Space Act of 1958 (72 Stat. 435; 42 U.S.C. 2457).
