ABSTRACT:
A new geometry for the propagation elements of a field-access magnetic bubble memory is disclosed which is tolerant of relatively wide gaps between elements and lower drive fields. The elements have shapes which define bubble "traps" operative to hold bubbles for relatively high efficiency transfers between elements. In alternate embodiments, the elements have an L-shape or a "pickaxe" shape.
