Abstract :
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 (FI2TD). 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
