High density magnetic bubble chips with major/minor loop designs having double period propagators in the input and output major tracks result in minor loops separated by one drive field rotation instead of the usual two. As a result, bubbles arrive at the detector on every cycle, and an every-bit-detect scheme is required. However, detector performance can be improved with the use of a predetermined zero bit position to compare the bubble signal to. As a result, zero bit positions must be inserted into the bit stream.
