Abstract:
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.
