| Abstract(in English) | Some quantitative measurements on magnetically recorded patterns by magnetic force microscopy (MFM) have been recently reported. An MR head detects the magnetic field from media, while MFM detects differential of the magnetic field. Therefore MFM images may have some differences from MR head measurements in terms of the reproduced waveform. We theoretically compared the surface magnetic field with its differential using a simple model for perpendicular recording patterns. The experimental values from MFM images are also compared with those by analysis. It was found that differential of the magnetic field have a large spacing loss factor for small d/λ, but the loss factor markedly decreases with increasing d/λ, while field strength itself decays obeying 54.6dB.(d/λ). A small spacing loss factor of about 45dB was obtained in MFM experiments. Consequently MFM signals are much enhanced in a higher density region. |
