CURVATURE OF PERPENDICULAR MAGNETIZATION TRANSITIONS ACROSS TRACK

抄録

  The nature of the perpendicular recording process at track edges is of interest in the design of very high track density recording systems. Recording experiments carried out on a large-scale model exhibit across-track curvature of the recorded transitions of perpendicular magnetization. Calculations using a simple three-dimensional analytical recording model suggest that the curvature is associated with the across-track variation of the demagnetizing field produced by the recorded magnetization pattern.
