ABSTRACT:
A method of manufacturing a magnetic head includes fabricating a magnetic block having a lamination of magnetic alloy films and nonmagnetic substrates, and cutting the magnetic block into two bars to obtain magnetic core halves. A nonmagnetic film is formed on a surface of each of the core halves. The core halves are joined by adjoining the surfaces having the nonmagnetic film and then heating the thus adjoined core halves. Additionally, a magnetic field is applied rotating in a plane parallel to a plane of the magnetic alloy films. The joined core halves is then cut into a specified width, and a wire-winding window is machined therein.
