Abstract
PURPOSE: To increase the erased phase margin and to reduce the value of produced current at the same time, by locating the projection to the cylindrical magnetic domain transfer pattern and placing the conductor pattern so that this projection is surrounded.
CONSTITUTION: The U shaped conductor pattern 4 is located so that the projection 3 of the YY type drive pattern 2 can be surrounded. In this case, the distance between centers of the conductor pattern 4 is made a little greater than the diameter of the cylindrical magnetic domain 5. Since the cylindrical magnetic domain 5 is fixed more than 1/4 period of external magnetic field Hr with the projection of the Y type pattern, without extending the distance between centers of the conductor 4, the phase margin of the erase unit operation can sufficiently be obtained widely. Further, since the distance between centers of the conductor pattern 4 can be narrowed, the current required at the generation of cylindrical magnetic domain can be smaller. Accordingly, without increasing the produced current, the generation and erase of cylindrical magnetic domain can be made with wide phase margin.
