1. A magnetic head comprising:

  • a plurality of read elements each comprising a first magnetic layer having a pinned magnetization direction, a second magnetic layer opposing the first magnetic layer via an insulating layer therebetween and having a free magnetization direction, and an independent electrode in contact with the first and second magnetic layers to output a reading signal from each read element;

    wherein at least two of the plurality of read elements are arranged such that both of the first magnetic layer and the second magnetic layer of each of the at least two read elements cross an arbitrary line and the first magnetic layers of the at least two read elements are different in magnetization direction with respect each other.
