Abstract
PURPOSE:To simplify the production process and to enable mass production by molding a laminated body consisting of two thin magnetic strips and a thin iron or iron-base film which has the saturation magnetic flux density higher than the saturation magnetic flux density of the two magnetic strips and is sandwiched by the thin magnetic strips to a prescribed shape. CONSTITUTION:The laminated body 10 is formed of the two thin magnetic strips 11, 12 having the high saturation magnetic flux density and the thin iron or ion-base film 21 which has the saturation magnetic flux density higher than the saturation magnetic flux density of the strips 11, 12 and is sandwiched by the strips 11, 12. A coil for excitation is wound on a one side of a head piece formed by molding this laminated body 10 to the prescribed. Saturation of the head core is then obviated even if magnetomotive force is increased. Since the head piece can be taken out by a masking and etching stage after the laminated body 10 consisting of the thin films is formed, plural pieces of the heads are produced simultaneously. The method suitable for mass production is thus obtd.
