TOKYO, Jun 10, 2021 – (JCN Newswire) – Showa Denko K.K. (SDK; TSE: 4004) has contracted Seagate Singapore International Headquarters Pte. Ltd. (Seagate) to collectively develop next-generation hard disk (HD) media for information recording using Heat Assisted Magnetic Recording (HAMR[1]) technologies, which is a next-generation data recording method for hard disk drives (HDDs).SDK has generated FePt-based fresh magnetic material and technologies to mass-produce HAMR-technology-based HD media using this new magnetic material. This FePt-based fresh magnetic material has ultra-high ordering temperature, which has been thought to be hard to realize on the surface of HD media coated with conventional magnetic material.Seagate has outdistanced additional HDD manufacturer in technological development of HAMR-based HDDs. Under the joint development arrangement, SDK and Seagate have entered into, Seagate will evaluate the FePt-based fresh magnetic substance developed by SDK and/or SDK/Seagate collaboratively. We expect this cooperation will accelerate technological development initiated by both companies.The amount of communicated data generated will likely increase drastically due to different factors such as the start of 5th generation (5G) cell communication solutions, the spread of Internet Things (IoT), teleworking, and the progress and expansion of Digital Transformation. Consequently, it is now a more important task for HDD manufacturers to boost storage capacity per unit of HDD to be used in data centers.Showa Denko Group’s Vision is to create it a”KOSEIHA Company” (a bunch of KOSEIHA Businesses which can maintain profitability and stability at elevated levels over a long period), and we place our HD media company among heart KOSEIHA Businesses. As the largest independent HD media provider in the world, SDK will keep on placing the top-performance HD media equipped with next-generation recording technologies such as HAMR and MAMR (microwave assisted magnetic recording) to the market prior to others in accord with its motto of”Best in Class,” thereby contributing to the expansion of HDDs’ storage capacities. [1] HAMR (Heat Assisted Magnetic Recording) is a technology to record data on the surface of HD medium with high density by heating membrane of magnetic material locally in order to solve so-called”trilemma of magnetic tape,” namely, simultaneous realization of three properties such as small magnetic particles, thermal fluctuation resistance, and easiness to be magnetized. Theoretical maximum data storage density achievable with conventional magnetic recording technology is 1. 14Tb/in2. On the other hand, theoretical data storage density achievable with HAMR technology is said to be about 5 to 6Tb/in2. Therefore, it is expected possible to equip a unit of 3.5″ HDD with storage capacity of approximately 70 to 80Tb.About Showa Denko K.K.Showa Denko K.K. (SDK; TSE: 4004, ADR:SHWDY) is a major producer of chemical products operating from heavy industry to electronics and computers.
