System requirements and bubble device capabilities

The possible uses of magnetic bubbles in memory systems have been discussed before. Dynamic data reallocation, a technique that may open wider areas of use for bubble memories, is discussed in a companion paper. Another challenging area of application appears in digital switching networks as suggested before. The bubble functions required in such a network may be largely the same as those necessary in the realization of a mass memory. After reviewing the data on the characterization of the devices that have been designed to perform these functions, it may be concluded that a bubble network is feasible.
