Showa Denko K.K. has contracted with Seagate Singapore International Headquarters Pte. Ltd. (Seagate) to jointly develop next-generation hard disk (HD) media for data recording with Heat Assisted Magnetic Recording (HAMR*1) technology, which is a next-generation data recording method for hard disk drives (HDDs). SDK has developed FePt-based new magnetic material and technology to mass-produce HAMR-technology-based HD media with this new magnetic material. This FePt-based new magnetic material has ultra-high ordering temperature, which was thought to be difficult to realize on the surface of HD media coated with conventional magnetic material.
