Abstract
PURPOSE:To improve recording/reproducing output characteristics by providing the titled production with a process for working the film forming face of a piece to surface roughness more than a prescribed value prior to a film forming process and a process for removing working distortion generated in the piece by said formation. CONSTITUTION:The production has the process for working the film forming face of the ferrite piece 1 to the surface roughness more than the prescribed value prior to the film forming process and the process for removing working distortion generated on the piece by the surface roughness working process. Thereby, an interface between a magnetic alloy thin film 2 formed on a face opposed to a magnetic gap G of a magnetic core 6 and magnetic oxide has surface roughness more than the prescribed value and a fine rugged face from which working distortion is removed and a part which is not parallel with the magnetic gap G by microscopic observation is increased. Consequently, an effect due to the magnetic gap G can be suppressed and excellent recording/ reproducing output characteristics can be obtained.
