Abstract

Domain holders are located in front of the entrance of loops in a long serial magnetic bubble domain chip, to overcome problems experienced with discs located within the entrance of the loops. Due to the permitted size of the discs, in many instances, the bubbles captive thereon have been unable to seal off defective loops through repelling incoming bubbles.

Captive Bubble Domain Holder

Domain holders are located in front of the entrance of loops in a long serial magnetic bubble domain chip, to overcome problems experienced with discs located within the entrance of the loops. Due to the permitted size of the discs, in many instances, the bubbles captive thereon have been unable to seal off defective loops through repelling incoming bubbles.

Holder 7, having transfer current line 8 threaded therethrough, is positioned outside the normal propagation path 1, 2, 3', 4', 5', 6', 5 and 6. A bubble is located on holder 7 if the propagation path has no defects.

If there are defects, then no bubble is located on holder 7. This is the opposite of the way discs are utilized. If there is no bubble located on holder 7, then due to 3 being slightly more attractive than 3', the alternate path 1, 2, 3, 4, 5, and 6 is followed by a subsequently propagated bubble.
