Abstract
PURPOSE: To reduce the generated bias magnetic field component, by installing the bias magnetic field compensating conductor layers having a fixed width each in parallel at the driving layer of a current access type magnetic bubble memory and then applying the compensating current of a prescribed current density.
CONSTITUTION: The bias magnetic field compensating conductor layers 33 having a ratio of 5W20 to the width of the bubble driving conductor layer 31 are installed in parallel with an insulated gap secured inbetween at the both sides of the layer 31 of a current access type magnetic bubble memory at nearly the same level as the layer 31. Then the compensating current of a fixed direction and having a current density of a ratio of 1.5W4.5 to the current density of the access current of the layer 31 is applied to the layer 35. As a result, a large bias magnetic field component generated via the layer 31 can be reduced greatly to increase the working margin. Thus the area occupying the chip 1 is increased for the magnetic domain element.
