Abstract: A magnetic bubble domain storage system comprising an array of rows and columns of logical chips are organized into logical half-chips with even numbered bits in one half-chip and odd numbered bits in the other half-chip. Alternating rows of half-chips are used for storing even numbered bits and odd numbered bits, respectively. Each half-chip has its own bubble domain generator, but a common generator current line serves all generators for a row of even half-chips and all generators for a row of odd half-chips. Thus, information is written into even half-chips and odd half-chips at the same time by pulsing the generator current line common to a row of even half-chips and a row of odd half-chips. Each half-chip has a sensing element and all the sensing elements corresponding to a row of half-chips are connected in series.
