Abstract
In a magnetic bubble memory device comprising a number of magnetic bubble propagation paths each including magnetic bubble propagation bit segments arrayed in the direction of propagation of magnetic bubbles, the propagation paths being arranged in the direction perpendicular to the propagation direction of magnetic bubbles, d/.lambda..sub.x is set to less than 0.2, where .lambda..sub.x is the period of arrangement of the magnetic bubble propagation paths and d is the distance between close adjoining magnetic bubble propagation bit segments of adjacent magnetic bubble propagation paths.
