Abstract
A magnetic bubble store including at least two series of longitudinally oriented major shift registers and a rotating magnetic field for producing a displacement of the bubbles in the minor registers. The series of minor registers are respectively arranged on either side of a transverse boundary. The minor registers of each of the series are constituted by motifs defined by ion implantation in a magnetic garnet layer. On either side of the boundary, these motifs define complementary distributions of implanted areas and non-implanted area.
