To provide a magnetic head that is suited for high recording density magnetic read and write, and has little noise. A magnetic pinned layer is formed on a non-magnetic electrode layer via a first insulating layer, and a magnetic free layer is formed on a medium-side plane of the non-magnetic electrode layer via a second insulating layer. A circuit for flowing current between the non-magnetic electrode layer and the magnetic pinned layer via the first insulating layer, and a circuit for measuring voltage between the non-magnetic electrode layer and the magnetic free layer are connected to the magnetic free layer. The medium-side plane on which the magnetic free layer is formed may be a plane substantially parallel to the surface of the medium, or may be a plane tilted from the surface of the medium.
A magnetic read head comprising:
A magnetic read write system comprising a magnetic recording medium, a medium driving unit for driving said magnetic recording medium, a magnetic head performing read and write operations to said magnetic recording medium, and a magnetic head driving unit for driving said magnetic head to a desired location of said magnetic recording medium;
