Magneto-resistive head utilizing plural plates arranged with their easy axis parallel to recorded magnetic flux

摘要

A magneto-resistive (MR) head of a new structure provides a linear output according to the variation of a recording magnetic flux. The magneto-resistive head generates an electrical output corresponding to the variation of a recording magnetic flux recorded on a disk, and includes an MR element portion disposed in such a manner that the forward (easy) direction of the MR element portion parallels the direction of the recording magnetic flux, and conductors coupled to the MR element portion through which a measured current flows. The MR head has linear output characteristics with respect to the variation of the recording magnetic flux. Also, the MR head does not need a bias means as does the conventional MR head.
