ABSTRACT:
A permalloy detector for a magnetic bubble memory employs a stack of chevron elements astride the bubble path. Alternate ones of the elements are positioned at an angle to the path of bubble propagation smaller than the angle at which the remaining elements are positioned. The result is that one set of elements moves a stretched bubble to a position at which the remaining elements accomplish detection. The result is a clearer output signal which is relatively easy to detect.
