Abstract
A magnetic bubble memory chip comprises minor loops of a folded structure for storing information in the form of magnetic bubble domains, and input and output tracks for transferring the information into and out of the minor loops. The input and output tracks have a pattern repetition period that is four or more times as large as a fundamental period of each of the minor loops.
