Three dimensional magnetic recording analysis taking account of hysteresis

The authors describe a method for three-dimensional finite-element analysis taking into account of hysteresis. For the finite-element analysis, the T- Omega method is used in order to reduce the CPU time. To express the three-dimensional hysteresis, a curling model theory is used. In addition, this method is applied to video cassette recording. Numerical results are compared with experimental and numerical results obtained by two-dimensional analysis based on the A-OE method.<
