PURPOSE:To reduce the rubbing noise level by forming a thin film with a metallic magnetic material having its saturated magnetic flux density and permeability approximately equal to those of the ferrite at a part where the butting surface between a pair of magnetic core halves has a contact with a magnetic gap with a magnetic head containing said core halves made of the ferrite. CONSTITUTION:The magnetic core halves 1a and 1b are made of the ferrite having high permeability. The metallic magnetic thin films 7 and 7 made of a metallic magnetic material having a smaller Young's modulus and larger internal loss than the ferrite are provided on the entire part of a butting surface of both halves sandwiching a magnetic gap G as well as on the inside surface of a groove 3. As a result, the stress produced inside the ferrite by the frictional force generated when a magnetic recording medium rubs the ferrite of the magnetic core is absorbed and reduced. Thus the rubbing noise level is reduced.
