Serriform Strip Crosstie Memory.
Abstract
The patent application provides a thin-film magnetic memory strip having oblongly symmetric serriform margins and using stationary domain walls containing Bloch lines, crossties, and Neel walls as shift register tracks for storage and propagation of binary information, and an etching process for making the strips. The edge effect of the margin serrations upon magnetization, a form of shape anisotropy, inherently defines memory cell boundaries in the domain walls, thereby giving the crossties and Bloch lines preferred locations and allowing the use of a simplified propagation scheme.
