Abstract
PURPOSE:To improve S/N ratio by forming a conductive layer for shielding in the form of enclosing thin-film elements near the side opposing to a medium of the thin- film elements. CONSTITUTION:A conductor layer 22 of copper, aluminum, etc. is formed by a method such as vapor deposition plating on a silicon substrate. Next, the 1st insulation layer 17 is formed and upper/lower magnetic films 13, 12 and thin film conductors 11 are formed thereon. Further, the 5th insulation layer 23 is formed of silicon dioxide or the like thereon. Next, a shield forming layer 16 is formed in the region adjacent to the upper/lower magnetic films 13, 12 forming the track width of the thin-film elements. When a conductive layer 24 for shielding is made over the entire surface of the thin-film elements, the layer 24 and the layer 22 contact. Namely, the conductor 24 is enclosing the thin-film elements and this process is formed for each thin-film elements. With such construction, the shield effect against the false signal of the conductor parts acts effectively and S/N ratio is improved.
