ABSTRACT:
A data track formed of a strip of magnetic film having substantially zero uniaxial anisotropy, i.e., isotropic, for a cross-tie wall memory system is disclosed. The data-track-defining-strip of isotropic magnetic film utilizes its shape, i.e., its edge contour induced anisotropy, rather than its easy axis magnetic field induced anisotropy, to constrain the cross-tie wall within the planar contour of the film strip. The use of the shape induced anisotropy of an isotropic strip of magnetic film permits the use of nonlinear, i.e., curved, data tracks which curved data tracks were not permitted by the prior art cross-tie wall memory systems that were limited to the use of anisotropic magnetic film.
