Bubble domain storage using improved transfer switch

Abstract From the Canadian patent

Abstract of the Disclosure, A magnetic bubble domain storage device comprising a plurality of storage shift registers and at least one major shift register which, serves to provide bubble domains to the storage register and to receive bubble domains from the storage registers. A novel transfer switch or, gate, is located between each of the storage registers and the major register? which is typically configured in the conventional major/minor loop type of storage organization. This transfer switch can be made using single level masking or multiple level masking and is characterized in that the locus of bubble domain propagation paths through the switch element generally defines the letter …
