We report on the fabrication of high coercivity magnetic force microscopy tips for magnetic images. The CoPt permanent magnetic crystallites are prepared by magnetron sputtering followed by annealing at 700°C in an argon atmosphere. We present the magnetic images of a thin-film recording head and written patterns of a recording disk taken with high Hc CoPt MFM tips.
