摘要： A highly density magnetic bubble memory device has bubble propagation paths having different pattern periods. The distance between a propagation path having shorter period and a magnetic film for holding magnetic bubbles is made smaller than that between propagation path having longer period and the magnetic film. An insulating layer formed between the propagation path and the magnetic film through another insulating layer has a declining slope having an angle of 60.degree. or less, thereby ensuring steady propagation of the magnetic bubbles along the propagation path.

摘要： A hybrid magnetic bubble memory device includes a first magnetic bubble propagation tracks formed of a portion of the boundary between first and second regions of a magnetic medium film having uniaxial anisotropy and adapted to be applied with a magnetic field in a direction perpendicular to the magnetic medium film to generate magnetic bubbles therein, and a second magnetic bubble propagation tracks formed of a soft magnetic material film on the magnetic medium film and connected with the first magnetic bubble propagation tracks. The first region is implanted with ions under ion-implant conditions different from those for the second region, and thus the above boundary is produced. The boundary between the first region and the second region is bent at junctions for transferring a magnetic bubble from the second magnetic bubble propagation tracks to the first magnetic bubble propagation tracks, to divide the boundary into a boundary portion for propagating a magnetic bubble and another boundary portion having no connection with magnetic bubble propagation, and an angle between the boundary portions at the bend in the boundary is in a range from 45 to 180 degrees.
