Abstract
PURPOSE:To improve effect by equipping magnetic materials, such as ferrite, which are arranged so that they come into contact with lamination cores for forming tracks in common, on the flank of the lamination cores. CONSTITUTION:A head consists of lamination cores 1a, 1b, and 1c, spacers 2a, 2b, and 2c, and magnetic materials 3a, 3b, and 3c. The magnetic materials 3a and 3b,such as ferrite, are arranged in common contact with the flanks of the lamination cores 1a, 1b, and they are reinforced and connected together magnetically. Thus, variance among tracks is reduced and the area of connection with a winding part 4 is increased, thereby reducing magnetic loss.
