Magnetic torque analysis has been carried out for CoNiPt, CoCrTa/Cr and CoCrPt/Cr thin-film media. The magnetic field Hgraink, where the rotational hysteresis loss vanishes, remained almost constant in each material, independent of the coercive force Hc. Only in the CoCrTa media no clear correlation between the rotational hysteresis integral and Hc was observed.
