Magnetic bubble circuits are a new type of integrated circuit employing movable magnetic domains. Because of the internal structure of magnetic bubble circuits, the most obvious applications are those involving serial data coding or storage. The report describes the operation of bubble devices and presents a detailed design of a bubble memory system for bulk data storage. This system is shown to have special application to satellite memory systems as a substitute for the present tape recorder memories. In this application the magnetic bubble memory appears to be superior to the tape recorder in power, size, and reliability. A 6 megabit bubble memory is described and a comparison made with the 6 megabit tape recorder used on the SAS-A satellite. Author
