Abstract
The invention relates to a magnetic bubble store. This store comprises a magnetic garnet layer (1), in which can be formed magnetic bubbles, which are respectively localized by cells. Each cell comprises a pair of localization windows (2, 3), respectively cut from conductive strips (4, 5) of a pair of conductive strips. These strips are insulated from one another and from the garnet and can be respectively traversed by currents (I.sub.1, I.sub.2) for displacing the bubble optionally located in the cell and means (21) for detecting each bubble. The memory is characterized in that the strips of each pair of strips have directions (X, Y) perpendicular to one another, the currents (I.sub.1 I.sub.2) in said strips being respectively parallel to said directions (X, Y).
