ABSTRACT:
The quantity of impurities in a magnetic material is decreased to produce a magnetic material with good quality, and a decrease in the cost of the magnetic material is realized by desulfurization. A magnetic raw material for metallic thin film magnetic recording media which contains sulfur more than 20 ppm is desulfurized to obtain the magnetic material for metallic thin film magnetic recording media with the sulfur content adjusted to 20 ppm or below, and a metallic thin film magnetic recording medium having a magnetic layer vaporized thereon with the magnetic material is fabricated.
