Patent Number Title Of Patent Date Issued
6549369 Multilayer film core magnetic head with bonding glasses of differing thermal expansion coefficie April 15, 2003
A magnetic head includes a pair of magnetic core halves provided with at least metal magnetic films are combined together so that the metal magnetic thin films of one of the pair of magnetic core halves are abutted on the thin films of the other. A winding slot is provided in the abuttin
5948554 Magnetic head September 7, 1999
The ZnO amount contained in the ferrite is lowered more than those of conventional ones to increase the mean coefficient of thermal expansion of the ferrite. Thus, a difference between the mean coefficient of thermal expansion of the ferrite and the mean coefficient of thermal expansion
5945227 Magnetic head August 31, 1999
The absolute values of the apparent magnetocrystalline anisotropic energy K1 is made large to increase the absolute value of the crystal magnetic anisotropy energy by adjusting the content of Fe.sub.2 O.sub.3 in the single crystal ferrite to 50 to 52 mol % or 55 to 58 mol %, thereby the
5856899 Magnetic head January 5, 1999
The magnetocrystalline anisotropic energy Kl is set to not more than 100 J/m.sup.3 and the absolute value of the magnetostriction in the <100> direction, as the magnetic circuit direction, is reduced by appropriately selecting the ferrite material composition. Since the magnetocrys
