PURPOSE:To offer a high frequency head taking an amorphous magnetic member having a good magnetic characteristic as core main bode by butting amorphous magnetic thin core halves, coating a reinforcing member from both sides of the core halves and filling a resin between both core halves for solidifying and uniting the resin to one body. CONSTITUTION:In the figure, 1 is the core main body consisting of the butted core halves 2, 3 formed with non-laminated thin amorphous magnetic plates (24mum thick), 4, 4 are a pair of reinforcing members holding the core main body from both sides, and 5 is a bonding member layer (<=2mu in layer thickness) impregnated and solidified between the core main body 1 and the reinforcing body 4. The core halves 2, 3 has a groove 6 onto which a coil is wound at the butted face and is provided with a nonmagnetic spacer 7 forming a front gap at the upper part of the groove. The reinforcing members 4, 4 are formed with a glass member, a through-hole 8 is penetrated at a position opposing to the groove 6 so that the coil is wound with balancing. A contact face 9 of the magnetic head in opposition to the magnetic tape is polished with chamferring, so as to ensure the matching to the magnetic tape at running. |
