Magnetic head and magnetic recording/reproduction device

A magnetic head comprising:

• a magnetic yoke taking in a signal flux from a magnetic recording medium, the magnetic yoke having a first yoke member, a second yoke member and a magnetic gap, the magnetic gap located between the first and second yoke members at a medium facing surface;
• and
• a magnetoresistance-effect element disposed to have magnetic contact with the first and the second magnetic yoke and detecting the signal flux transferred from the magnetic yoke,
• at least one of the first and the second magnetic yokes having a granular magnetic film, the granular magnetic film transferring substantial part of the signal flux to the magneto-resistance effect element.

A magnetic head comprising:

• a magnetic yoke taking in a signal flux from a magnetic recording medium, the magnetic yoke having a first yoke member, a second yoke member and a magnetic gap, the magnetic gap being located between the first and second yoke members;
• and
• a magneto-resistance effect element detecting the signal flux transferred from the magnetic yoke,
• the first and second yoke members being disposed on substantially a same plane surface and having a plurality of magnetic domains, each of the magnetic domains having a main magnetization direction substantially parallel or antiparallel to a normal to the plane surface.

A magnetic recording/reproduction device comprising a magnetic head reproducing information that is stored in a magnetic recording medium,

• the magnetic head including:
• a magnetic yoke taking in a signal flux from a magnetic recording medium, the magnetic yoke having a first yoke member, a second yoke member and a magnetic gap, the magnetic gap being located between the first and second yoke members at a medium facing surface;
• a magneto-resistance effect element detecting the signal flux taken from a magnetic recording medium;
• and
• a granular magnetic film disposed between the magnetic yoke and the magneto-resistance effect element, the granular magnetic film having a magnetic contact with the magnetic yoke and transferring the signal magnetic flux taken by the magnetic yoke to the magneto-resistance effect element.
