Abstract
Detection device for a magnetic bubble memory having a detection zone (6) constituted by rows (7) of patterns (8) suitable for the propagation of bubbles in strip form, as well as a transition zone (10) making it possible to draw out the bubbles in strip form. The transition zone 10 has at least one row (18) of soft magnetic material patterns, (18) which has at least one central pattern (22) and a second pattern (24) adjacent to the central pattern (22). The central pattern (22) has a first part (22a) able to guide a magnetic bubble and a second part (22b) able to aid the propagation of a bubble in strip form. The second pattern (24) is able to aid the propagation of a bubble in strip form, while not disturbing the propagation of a bubble along the first part (22a) of the central pattern (22).
