ABSTRACT:
In a magnetic bubble memory device comprising a number of magnetic bubble propagation bit segments arrayed to form a magnetic bubble propagation path and having each a pattern of a length L in a direction of propagation of magnetic bubbles being less than 3.4 D where D is the average diameter of the magnetic bubbles and is not greater than 2.0.mu., the height H of the pattern of the magnetic bubble propagation bit segments in a direction perpendicular to the propagation direction of magnetic bubbles is set to be in a range of 0.75.times.L.ltorsim.H.ltorsim.1.1.times.L.
