ABSTRACT:
A magnetic bubble domain device for recording information on a magnetizable recording medium including a shift register filled with a series of bubble domains coded in accordance with the information to be recorded, the whole bubble domain pattern being printed, in combination with a magnetic transfer field, in one time on a recording medium, new information replacing the old information by shifting of the bubble domains in the register.
