Abstract

PURPOSE: To carry out the transfer of a bubble smoothly along a pattern in a low intrasurface rotating magnetic field by making different the thickness of the film in the prescribed range of a drive layer formed on the retaining layer of a bubble magnetic domain.
CONSTITUTION: This element consists of a layer 12 retaining a bubble magnetic domain 14, and a drive layer 11 having a intrasurface magnetizing composition. Along a periodical continuous pattern 19 formed in the drive layer 11 correspondingly to a magnetic field 16 rotating in a film surface, the bubble magnetic domain 14 is transferred into the remaining layer 12. In this case, the drive layer 11 is formed by removing a pattern part 19 from a single crystal intrasurface magnetizing layer produced on the retaining layer 12 ane the film thickness he of the drive layer 41 in a range of distance (a), which is twoWfour times as large as the bubble diameter from the end of the pattern is made larger than the film thickness hd of other layer 42.
