Abstract
The chevron elements of a detector stage of a magnetic bubble memory are interconnected in a manner to allow tailoring of the output signals produced in response to the presence of an elongated bubble. The tailoring is shown to allow a design which is characterized by an improved signal-to-noise ratio.
Claims2
A magnetic bubble memory comprising a layer of material in which magnetic bubbles can be moved, a magnetoresistive detector and means for moving said bubbles to said detector, said detector comprising a plurality of chevron elements, said elements being aligned along an axis transverse to the path of bubble movement, said chevron elements being interconnected by interlinking elements into a single magnetoresistive element, said interlinking elements being arranged in at least first, second, and third groups to link together pairs of adjacent elements in at least three different sets of corresponding positions.
