Rectangular concentric annular plastic inserts 1, 2 are part of field accessed magnetic domain device module M. Insert 1 acts as a bobbin for Z-axis coil 3 which allows variation in the bias field produced by the permanent magnets (PM) 13U, 13L. Insert 1 has seating pads 4 which coact with complementary seating pads 5 of insert 2. Substrate assembly A, which comprises pin carrier substrate 6, bubble domain chip 7 affixed to substrate 6, and orthogonal X and Y rotational coils 8 and 9 wrapped around substrate 6. is tilted at a predetermined angle alpha by pads 4, 5.
