The invention relates to a readout device for magnetic bubbles. According to the invention, it includes a monoaxial magnetic layer (1) on which are placed a magnetoresistive readout element (4) and a magnetic bubble spreading circuit (3) in the form of two conductors (6 and 8) which are rectangular, insulated and arranged one above the other; recesses (11 and 12) with a length equal to kd, k > 1 and d being the diameter of the magnetic bubble, are made on the large opposing sides of the conductors (6 and 8); the boundary (15 or 16) of the recess (11 or 12) of the conductor (6 or 8) is parallel to the larger side of the conductor (6 or 8) and coincides with the respective axis of symmetry (9 or 10). The invention applies in particular to magnetic-bubble memories. <IMAGE>
