Abstract

PURPOSE:To increase resistance to an external disturbing magnetic field while simplifying a control circuit for a rotating driving magnetic field, by nearly equalizing the intensity of the hold magnetic field of a magnetic bubble memory device to that of the rotating driving magnetic field. CONSTITUTION:A magnetic bubble memory element 6 is arranged at an angle theta to magnets 9 and 10 for generating bias magnetic fields, and the intensity of its in-surface hold magnetic field is nearly equalized to that of a rotating driving magnetic field. With the regard to the relation between the in-surface hold magnetic field and driving magnetic field for securing start-stop operation, the rotating driving magnetic field draws a shown Lissajour' figure; when a current is flowed through neither an X coil nor an Y coil, no magnetic field is generated when currents are flowed through the X and Y coils, a rotating magnetic field is established without spiraling.
