ABSTRACT:
A magnetic bubble memory has a first bubble propagation track formed with an ion-implanted pattern and a second bubble propagation track formed with permalloy members connected to each other to form a storage loop. The arrangement is such that a position of an attractive magnetic pole created in one of the permalloy members coincides with a position of an attractive charged wall appearing in the ion-implanted layer at a junction of the first and second bubble propagation tracks when a driving magnetic field is in a particular range of direction.
