Abstract:
A magnetic head of an embodiment has first and second magnetic shields, a stack, a side shield, and an antiferromagnetic layer. The stack has a pin layer, a nonmagnetic layer, and first and second free layers. The second free layer is antiferromagnetically exchange coupled to the first free layer and is exchange coupled to the antiferromagnetic layer. The side shield is exchange coupled to the antiferromagnetic layer.
