Abstract
A detector structure for contiguous-disk bubble devices has a non-ionimplanted elongated bar, a hairpin conductor and a thin-film magneto-resistive element. The elongated bar is positioned in spaced relation to a large period element at the end of a propagation loop. The elongated bar extends both above and below the large period element and prevents the bubble from passing around the element. The hairpin conductor is positioned over the edge of the bar that faces the end period element. The magneto-resistive element is positioned parallel to and at the center of the hairpin conductor.
