ABSTRACT:
A magnetic bubble memory chip is arranged in such a way that the major surface of the chip will not cross perpendicularly with the external bias magnetic field to generate a component of the bias magnetic field which is parallel to the major surface. This component is added to the rotating magnetic field within the chip major surface and the intensity of a resultant rotating magnetic field is shifted to the start/stop direction of this rotating magnetic field. Of the basic elements incorporated in the chip, the basic elements which operate stably in a comparatively intense rotating field is operated in synchronism with the phase of the start/stop direction of the rotating magnetic field in order to ensure stable operation of all the basic elements under the decreased intensity of the external rotating magnetic field.
