ABSTRACT:
The magnetic bubble memory device of this invention is arranged such that a magnetic bubble detector and a nucleation type magnetic bubble generator in a chip are made to operate at different phases of the same operation cycle of a rotating magnetic field. Therefore, the operation time of the magnetic bubble detector and the operation time of the nucleation type magnetic bubble detector are completely separated from each other, although they are involved by the same cycle of operation of the rotating magnetic field. Consequently, the magnetic bubble detector can perform the detecting operation, without being affected by large amounts of noise which are generated during the operation of the nucleation type magnetic bubble generator.
