TDK in China

SAE Magnetics (HK) Ltd., a TDK group company, was established and headquartered in Hong Kong in 1980, and acquired by TDK in 1986. SAE has evolved to become one of the world's leading independent manufacturer magnetic recording heads for hard disk drives.


With its global technology teams in areas covering every aspects of magnetic recording heads including magnetic materials, magnetic multi-layer and head structures, wafer fabrication and ultra-precision manufacturing technologies, SAE is committed to deliver state-of-the-art magnetic recording technologies to the disk drives industries. The manufacturing of SAE begins from wafer fabrication that fabricates magnetic recording heads with magnetic multi-layer structures in nanometer regime. While the wafer fabrication of SAE takes place mainly in the United States, the bulk of it’s manufacturing in which wafers of magnetic recording heads are assembled into head sub-assemblies, namely Head Gimbal Assembly (HGA) and Head Stack Assembly (HSA), are based in two modern manufacturing facilities located in Dongguan, PRC. Founding on the core competence established in the business of magnetic recording heads, SAE has made successful business diversification to contract manufacturing of electronic components beginning from 2000.
