摘要： A recording element supported by a slider includes a non-magnetic film and a magnetic pole film. The non-magnetic film has a depression whose inner surface is provided with an amorphous electrode film used as a plating seed film. Above the electrode film, the magnetic pole film is grown by plating. The magnetic pole film may be either an electroplated film grown on the electrode film to have a maximum crystal grain size of 20 nm or less or an electroless plated film. This decreases coercive force of the magnetic pole film.

Thus, the magnetic multilayered film has the large exchange-coupling magnetic field and MR ratio and MR sensitivity. The magnetic multilayered film may be applied to a magnetoresistance effect element which may also applied to a magnetoresistance device, such as, a magnetoresistance effect type head. The magnetoresistance effect element having such a magnetic multilayered film is capable of obtaining high outputs. The magnetoresistance effect type head having such a magnetoresistance effect element which is excellent in current efficiency and capable of detecting signals magnetically recorded in high density, particularly in ultrahigh density exceeding 3 Gbit/inch.sup.2 and further obtaining large outputs.
