ABSTRACT:
Boundary protrusions or kinks are integrally formed along the perimeter of a magnetic layer of a magnetic transducer for nucleating a predetermined domain pattern in the magnetic layer. These protrusions or kinks behave as domineering pinning sites for the domain walls, overriding other factors such as manufacturing tolerances or external magnetic field, for establishing a stable magnetic domain pattern. As arranged, various kinds of noise encountered during the normal operations of the transducer are significantly reduced, as the noise related problems originated from the magnetic domain instabilities in the magnetic layers are substantially curtailed.
