Abstract

A bubble memory module 10 has a top yoke plate 12 and a bottom yoke plate 14. Between the two ends of plates 12 and 14 are magnets 16 and 18. Positioned in magnets 16 and 18 are adjustable magnets 20 and 22. Rotating magnets 20 and 22 from the original position decreases the bias field to provide a variable bias field.
