Magneto-resistive head including a film of hard magnetic material |
摘要 |
A hard magnetic thin film magnetized in one direction is disposed on or in the vicinity of a magneto-resistive element upon which inclined electrodes are formed. A magnetic field from the hard magnetic film magnetizes the magneto-resistive element stably so that the element has a single magnetic domain. Thus, the magneto-resistive head is remarkably stable with respect to the disturbance magnetic field and inhibits Barkhausen noise from being produced. As a result, the magneto-resistive head reproduces stably and with an improved S/N ratio.
