Abstract
A side feed expander for magnetic bubble devices is disclosed. The side feed expander includes a row of expander elements and an input propagation element associated with one of the sides of an expander element in the row of expander elements. In a preferred embodiment, the input element is associated with the apex portion on one side of one of the expander elements. In another embodiment one propagation element is associated with the side of an expander element on one end of the row of the expander and a second propagation element is associated with the side of an expander element positioned on the other end of the row. A side expander permits the dummy sensor to be positioned in several positions, including the opposite end of the expander from where the active sensor is located.
