Saehan Media started to produce iron oxide first ever in Korea in 1987. From then, the producing scale has increased to 700 tons per month and it is exported to Europe and South East Asia. Our iron oxide claims world best as it is granulated to apply as much as magnetic body for high recording density per unit size when applying video tape and excellent magnetic force and black degree that keeps same picture quality even its thin application.           1986. 10 Established factory for producing iron oxides 1993.12 Improved magnetic iron oxide for 이분산성video (EP-280 Series) 1994.12 Developed iron oxide for audio (EP-280 Series) 1997.01 Developed iron oxide for high density recording granulated video (EP-320 series) 1999.05 Developed iron oxide for high generating power / thin film coating video (EP-288M,EP-350M Series) 2000.08 Developed magnetite for toner of mid-speed copying machine (SMT-2000) 2001.12 Developed magnetite for toner of laser printer and high-speed copying machine (SMT -01S, 02H)
