The magnetization distributions of recording layers recorded by magnetic head writing and magnetic duplication were calculated by the two-dimensional finite element method. The recording characteristics of the two methods were evaluated by comparing the magnetization distributions. In head recording, conspicuous bit shifts appeared when the recording current was optimal. In magnetic duplication, slight bit shifts were obtained when the strength of the applied field was greater than optimal. The reproduced output signals were calculated from the magnetization distributions of recording layers recorded by magnetic head writing and magnetic duplication. As a result, it was found that the output voltages of magnetic duplication were the same as those of head recording.
