Numerical analysis of a magnetic recording write head benchmark problem using the finite integration technique

A benchmark problem of a thin film magnetic recording write head, proposed by the Storage Research Consortium (SRC) in Japan, is simulated with implicit time-domain formulations for nonlinear three-dimensional magneto-quasi-static problems based on the finite integration technique (FI/sup 2/TD). Several numerical schemes adapted to this framework are presented to achieve the required solutions. The write head fields are simulated with good agreement to the measurements.
