PURPOSE: A head device of an HDD(Hard Disk Drive) is provided to improve a head performance by using an organic polymer, which has a low conductivity increasing speed even if foreign material is doped to some degree, as the material filling a gab between core poles on both sides of a magnetic head. CONSTITUTION: An air bearing surface is formed on a housing. A core(3) wound by coils(4) is fixed to one side of the air bearing surface. The core is separated into one side pole(3a) and other side pole(3b). To form a magnetic stray flux, the organic polymer having a low conductivity fills the gab(5) formed between the poles. The organic polymer is polyethylene, polypropylene, and a polyimide.
