Modeling of magnetic recording heads using 2-D and 3-D finite element analysis was investigated for metal-in-gap and thin-film heads. It is confirmed that flux concentration as well as core thickness has to be carefully modeled when trying to solve in two dimensions. It is noted that nonlinear 2-D calculations of metal-in-gap heads are acceptable, however, 3-D analysis is strongly recommended for thin-film heads
