A magnetoresistive head (MR head) is applied to the readback process in perpendicular recording in comparison with longitudinal recording. A higher readback voltage, increased by a factor of nearly two, is obtained in association with the large recording magnetization of a perpendicular medium. D50 of the perpendicular medium is the same as the longitudinal one, which is thought to be a limitation of the MR head.
