Abstract
A method of producing a laminated amorphous alloy ribbon holding spool. The method includes providing amorphous alloy ribbon holding spools, each of which is wound with a single layer amorphous alloy ribbon, unwinding the single layer amorphous alloy ribbon from each of the amorphous alloy ribbon holding spools, making the single layer amorphous alloy ribbon travel with a laser being radiated thereto, to thereby simultaneously prepare single layer amorphous alloy ribbons having laser irradiation mark formed thereon, laminating the single layer amorphous alloy ribbons having the laser irradiation mark formed thereon to, thereby prepare a laminated amorphous alloy ribbon, and winding up the laminated amorphous alloy ribbon on a spool.
