Abstract

The method for manufacturing a laminate core of a magnetic head is for eliminating a thermal effect of magnetic characteristics during the manufacturing process and reducing a lead time. The method comprises a step of forming an oxide membrane on the surface of thin core plates, a step of arranging thin core plates, a step of welding a part of the thin core plates for forming a core block, a step of cutting the core block into laminate cores, and a step of annealing the cut laminate cores.
