Magnetic heads using a tunneling magnetoresistance effect

Abstract

A magnetic head having a tunneling magnetoresistance effect achieves high density recording by narrowing a writing track width of a recording head. The magnetic head has a tunneling magnetoresistance effect and includes a first non-magnetic layer disposed on a substrate. A regenerating magnetic head, anchored in the first non-magnetic head, includes a regenerating magnetic core. A regenerating magnetic gap of the regenerating magnetic head is directed toward a side face direction of the first non-magnetic layer. A tunneling magnetoresistance effect element is connected to the magnetic core. A magnetic flux from the tunneling magnetoreisistance effect element is applied to the tunneling magnetoresistance effect element. A second non-magnetic layer is disposed on the tunneling magnetoresistance effect element. A shield magnetic layer is disposed on the second non-magnetic layer. A third non-magnetic layer is disposed on the shield magnetic layer. A recording magnetic head is disposed on the third non-magnetic layer. A recording magnetic gap of the recording magnetic head being directed toward a side face direction. A magnetic field generating element supplies a magnetic flux to the recording magnetic core and generating a magnetic field in the recording magnetic gap.
